Hearing aids are electronic devices that amplify sound to help people with hearing loss. There are two main types - analog hearing aids amplify all sounds equally while digital hearing aids analyze sound and amplify different frequencies individually for clearer sound. Digital hearing aids break sound into 48 or more frequency bands and amplify each band as needed. Hearing aids come in several styles including custom-fit models that go completely in the ear canal or invisible models. Behind-the-ear models have the components behind the ear connected to an earpiece. Receiver-in-canal models place the microphone in the outer ear connected by a tube to a receiver in the ear canal.

Hearing aids
Hearing aids are small electronic devices that amplify sounds to help those with hearing loss. There are two main types - analog and digital. Analog converts sound waves into electrical signals while digital converts them into numerical codes. Hearing aids come in several styles including BTE (behind the ear), ITE (in the ear), and CIC (completely in canal) and aim to accommodate different levels of hearing loss. While technology continues to improve sound quality and features, hearing aids still help many experience the gift of hearing.

Hearing aids
A hearing aid consists of a microphone that picks up sounds and converts them to electrical signals, an amplifier that selectively amplifies those signals, and a receiver/speaker that changes the signals back to sounds and delivers them to the ear. It works by capturing sounds with the microphone, amplifying them with the amplifier, and sending the amplified sounds to the ear via the speaker. Earlier hearing aids were passive ear trumpons or horns that gathered and directed sound into the ear canal, while modern styles include behind-the-ear, in-the-ear, in-the-canal, and completely-in-the-canal devices. However, hearing aids can still have drawbacks like problems in background noise and discomfort from loud
Care and Maintenance of Hearing Aids
1) Battery issues are one of the main causes of hearing aid failure. Dead or defective batteries can cause weak output, distortion, feedback, and strange sounds from hearing aids.
2) To get the most battery life, wearers should develop a replacement schedule and disengage batteries when aids are not in use, like overnight. Batteries should also be inserted correctly with the positive side in the marked position.
3) Spent batteries should be thrown away rather than reused, as this can cause confusion. Short battery life usually indicates a defective battery or hearing aid problem requiring repair. Proper maintenance can help extend battery life.

Ear molds
This is a PPT to introduce different kind of hearing aid earmolds, ear impression and to choose the better earmold for different hearing loss levels.
A brief history of hearing aids
Hearing aid technology has advanced significantly over the past 200 years. Early hearing aids from the 1800s were simply ear trumpets or acoustic horns. The first electronic hearing aid was invented in 1900. Transistor technology arrived in the 1940s-1950s, allowing for smaller devices. Digital technology in the 1980s enabled programmability and multiple channels of amplification. Recent advances include wireless connectivity between devices, rechargeability, noise reduction algorithms, automatic features, and expanded bandwidth to better support speech recognition. However, fitting targets and understanding of the impaired auditory system have sometimes lagged behind technological capabilities.

Hearing aids & implantable hearing devices
Hearing aids and implantable devices can help people with hearing loss. Conventional hearing aids consist of a microphone, amplifier and receiver. They come in different styles like behind-the-ear or in-the-ear. Bone anchored hearing aids use bone conduction to bypass the outer/middle ear. Cochlear implants have an internal and external component and provide electrical stimulation of the auditory nerve for severe-profound loss. Implantable hearing aids use direct mechanical vibration of the ossicles. Candidates for these devices have moderate-severe loss and limited benefit from conventional aids.
Cochlear implant
Cochlear implants are surgically implanted devices that provide a sense of sound to those who are profoundly deaf or severely hard of hearing by bypassing damaged portions of the ear to directly stimulate the auditory nerve. They consist of an external portion containing a microphone, speech processor, and transmitter, and an internal portion containing a receiver, stimulator, and electrodes array. Cochlear implants are ideal for those with severe-to-profound deafness in both ears who have functioning auditory nerves but do not benefit from hearing aids. Risks include wound healing issues, infections, and device malfunctions.
Cochlear Implant
Cochlear implants are hearing prosthetics that can restore hearing for those with severe to profound hearing loss. They consist of external and internal components. The external components collect sound, process it and transmit signals to the internal implant. The internal implant stimulates the auditory nerve to provide a sense of sound. Candidates undergo testing, counseling and rehabilitation training. If approved, they have surgery to implant the device, then attend programming sessions to tune the implant to their hearing needs through mapping. Ongoing listening practice and support from a cochlear implant team helps the recipient learn to hear and understand sound.
Earmolds & acoustic couplings overview
Earmolds are custom molded to fit a patient's ear based on an ear impression in order to create a sound path from the hearing instrument to the ear canal and retain the hearing instrument. They come in occluding or non-occluding designs and use various materials, shapes, and bore sizes to optimize acoustic performance, comfort, and retention while fitting to the individual needs and preferences of the patient. Other coupling options besides custom earmolds include slim tubes with domes or receiver-in-canal hearing instruments.

Cochlear implant 1
Cochlear implants are surgically implanted devices that provide a sense of sound to those who are profoundly deaf or hard of hearing. They work by bypassing the damaged portions of the ear and directly stimulating the auditory nerve. The first modern cochlear implant was developed in 1961 and they have since become smaller and more advanced, allowing for implantation in younger children. Cochlear implants require extensive preoperative testing and evaluation to determine candidacy as well as postoperative programming and mapping to optimize hearing outcomes for each individual recipient.
Ototoxicity
Ototoxicity refers to damage to the inner ear caused by certain drugs or chemicals. Common ototoxic drugs include aminoglycoside antibiotics, loop diuretics, cytotoxic agents, antiprotozoals, antiepileptics, and environmental chemicals. Symptoms of ototoxicity include hearing loss, tinnitus, and balance disorders and can be temporary or permanent depending on the offending agent. Diagnosis involves assessing a patient's exposure history and test results. While there are no treatments to reverse damage, management focuses on rehabilitation and avoiding further ototoxic exposure.
Hearing Aid Care
The document provides tips for properly caring for hearing aids on a daily basis to prevent damage and malfunctions. It lists things like cleaning hearing aids and replacing batteries regularly, checking for wax buildup or cracks, storing aids in dry conditions overnight, and protecting them from moisture, heat, shock, and pets. Proper daily care can help hearing aids last longer between repairs.

It describes individual hearing aids, including the types (body-worn, behind-the-ear, in-the-ear), parts, how they function, and classifications. Group amplification systems discussed include hard-wire, induction loop, FM, and infrared systems. The induction loop and hard-wire systems are described in more detail regarding their components and advantages/disadvantages for classroom use.
Hearing aids and psychoacoustics.ppt
This document discusses hearing aid basics and advanced hearing aid technology. It explains that hearing aids have microphones, amplifiers and speakers to pick up and amplify sounds. Modern hearing aids use non-linear processing like compression and expansion to fit sounds within patients' dynamic ranges and mimic the cochlea's non-linearity. Frequency transposition moves inaudible high frequencies down an octave. Hearing aids may affect the natural resonance of the ear canal. Conductive hearing losses are easier to treat with hearing aids than sensorineural losses.
What are Digital Hearing Aids
Digital hearing aids work by converting sounds into digital signals and amplifying only desired sounds, like speech in noisy environments. They have multiple program memories and can be customized for users' specific hearing needs. Digital hearing aids are more advanced than analog aids due to features like precise sound amplification, noise reduction, and programmability through buttons or remotes. They use microprocessors to analyze sounds and modify them before delivering clear signals to improve the hearing experience over analog aids.

Care and maintenance of hearing aids and the types of implanted hearing loss each device addresses were also summarized.
Sensory Aids for Persons with Auditory Impairments
There are two basic approaches to assistive technology for auditory impairments: augmentation of existing pathways and use of alternative pathways. Augmentation involves amplifying sounds to improve reception of certain frequencies for those who are hard of hearing. Alternative pathways include tactile substitution, where sounds are felt through touch, and visual substitution, using displays to represent sounds. Examples of aids discussed include hearing aids, cochlear implants, visual alarms, and computerized speech and text.

Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

ABDOMINAL TRAUMA in pediatrics part one.
Abdominal trauma in pediatrics refers to injuries or damage to the abdominal organs in children. It can occur due to various causes such as falls, motor vehicle accidents, sports-related injuries, and physical abuse. Children are more vulnerable to abdominal trauma due to their unique anatomical and physiological characteristics. Signs and symptoms include abdominal pain, tenderness, distension, vomiting, and signs of shock. Diagnosis involves physical examination, imaging studies, and laboratory tests. Management depends on the severity and may involve conservative treatment or surgical intervention. Prevention is crucial in reducing the incidence of abdominal trauma in children.

8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.NVBDCP.pptx Nation vector borne disease control program

Hearing Aids
- 1. Hearing Aids
- 2. Hearing aid is an electronic device which amplifies sound to aid people who have a hearing problems
- 3. How a hearing aid works • A microphone picks up sounds. • Sounds are analyzed by the processing chip. • Processed sounds are sent to the amplifier. • Amplified sounds are sent to the loudspeaker. • Sounds are transmitted by the loudspeaker into the inner ear where they are transformed into electrical impulses. • Impulses are picked up by the brain where they are processed.
- 4. Difference between analog and digital hearing aids • Analog hearing aids make continuous sound waves louder. These hearing aids essentially amplify all sounds (e.g., speech and noise) in the same way. Analog hearing aids are becoming less and less common. • Digital hearing aids have all the features of analog hearing aids, but they convert sound waves into digital signals and produce an exact duplication of sound. Digital hearing aids analyze speech and other environmental sounds.
- 5. How digital hearing aids work Unlike analog aids, in digital hearing aids, sound enters the device is broken into multiple frequency bands. Each band is then amplified by the amount necessary to return the wearer's hearing to normal levels at that band. With digital technology, devices can now break sound into as many as 48 different bands. This feature makes the sound quality provided of a digital hearing aids far better than the analogue technologies.
- 6. Hearing Aid Models • Hearing aids are available in an extensive range of colors and sizes. Below chart shows some of the more common hearing aid models available.
- 7. Hearing Aid Categories Since hearing loss problems differ with people to people, there are many different models and styles of hearing devices are there to choose from. Generally Hearing aids can be placed in three categories. • Custom in-the-ear models (ITE) • Behind-the-ear (BTE) • Receiver in the ear (RITE)
- 8. Custom in-the-ear models Custom in-the-ear models are custom made to fit the contours of your ear canal. • Full shell • Half shell Canal • Mini canal • Completely in the canal (CIC) • Invisible in the Canal (IIC) Depending on the specific type, it may be more or less invisible in your ear.
- 9. Behind-the-Ear models (BTE) In this type, case of this hearing aid is hidden behind your ear and connected to a molded receiver that fits snugly in the outer ear. These hearing aids offer a volume control and/or push button that allow selection from multiple programs for specific performance situations.
- 10. Receiver-in-Canal This model combines the advantages of both the behind-the-ear and custom (in-the-ear) models. The microphone has been moved to the outer ear and is connected to the main body of the hearing aid by a thin transparent tube. The result is a virtually invisible hearing instrument that offers Open-fitting comfort and maximum wind noise suppression.
- 11. The Art of Hearing offers Digital Hearing Aids with incredible features and in all sizes.
- 12. The Art of Hearing is Perth's most affordable hearing aids
