A PA system consists of microphones, mixers, amplifiers, loudspeakers, and cables. Microphones capture sound and convert it to electrical signals which are sent to a mixer. The mixer allows combining of multiple audio sources and controls their levels before sending the signal to an amplifier. The amplifier strengthens the signal which is then sent to loudspeakers that convert it back to sound waves audible to the public. Crossovers and separate drivers are often used to optimize different frequency reproduction. Cables properly connect all the components.

Future Proof Surround Sound Mixing using AmbisonicsBruce Wiggins
1. Ambisonics allows for audio mixing and playback that is independent of speaker configuration, allowing a single mix to be played on various speaker arrays from 2 to 24 speakers.
2. B-format encoding with 4 channels (W, X, Y, Z) represents soundfields in a spherical harmonic basis and can be decoded to any speaker layout.
3. Recent free software plugins and file formats now make it practical to create, distribute and playback ambisonic audio mixes.
Audio spotlighting uses ultrasonic waves to create a narrow, focused beam of sound. It was invented by Dr. F. Joseph Pompei and allows specific listeners to hear sound without others nearby. It works by modulating an audio signal with ultrasonic frequencies, which through the nonlinearity of air generates new audible frequencies that can be controlled to carry the original audio signal. The technology has applications in museums, military communication, and safety situations where focused sound is needed without disturbing others.

It works by modulating an audio signal with ultrasonic frequencies, which through the nonlinearity of air generates new audible frequencies that can be focused into a beam. Its applications include targeted communication for safety officials in crowds and descriptive audio for museum exhibits without disturbing other listeners.
SoundSense is a scalable sound sensing framework designed for mobile phones that can perform tasks like conversation detection, activity recognition, and location classification using the phone's microphone. It addresses challenges of scaling to diverse environments, robustness to phone placement, and low-impact device integration. SoundSense extracts audio features, classifies sounds using machine learning models, and identifies patterns using Markov models. It can also adapt over time to identify new ambient sounds through unsupervised learning and user labeling. The lightweight SoundSense prototype runs continuously on iPhone with low CPU and memory usage to recognize a variety of sound events for context awareness applications.
Active noise cancellation uses a microphone to measure ambient noise and generate an inverted "anti-noise" signal to destructively interfere with and cancel out the noise. It works best for low frequencies while passive noise control using insulation is more effective at higher frequencies. Adaptive noise cancellation algorithms like LMS analyze noise waveforms and generate inverted signals through transducers to reduce perceived noise levels. Noise-cancelling headphones apply this technique to improve listening and sleep on planes by offsetting engine noise.

The document describes 70V paging systems and their components. 70V systems use a centralized amplifier with a 70V output to power speakers connected via long runs of wire. This high voltage, low current design minimizes power loss over the wires. The document discusses the benefits of 70V systems and explains their basic design and components, such as the centralized amplifier, speakers, taps, and interface devices. It also covers an alternative self-amplified paging system design that uses individual amplifiers built into each speaker powered by a 24V DC supply.
Audio spotlighting uses ultrasonic energy to create extremely narrow beams of sound similar to flashlight beams. It was invented in the 1970s and made commercially available in 2000. Audio spotlighting works by taking an original audio signal, modulating it with ultrasonic frequencies, and emitting it from an array of transducers. This allows the sound to be focused into a narrow, directed beam. Key components include a sound processor, frequency oscillator, modulator, and transducer. It has applications in areas like museums and ships where directable sound is useful. Advantages are directionality, no need for large speakers, and ability for nearby people to hear different sounds. Limitations include need for line of sight and inability to transmit over long
A basic sound system consists of an input device (microphone), a control device (mixer), an amplification device (power amplifier), and an output device (loudspeaker).
The primary goal of the sound system in sound applications is to deliver clear, intelligible speech, and, usually, high-quality musical sound.
Car audio systems typically have 4 main components: head unit, amplifier, speakers, and subwoofer. Upgrading these components, especially with a separate amplifier, can provide better sound quality than a factory system by delivering more clean power to properly drive aftermarket speakers and subwoofers. Using high-quality speaker components, as well as additional accessories like capacitors and power cables, can further optimize a car audio system for best sound reproduction.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2. What is a PA system?
An electronic amplification system used
as a communication system in public
areas
http://wordnetweb.princeton.edu/perl/webwn?s=pa%20system
3.
4. How do PA systems work?
Microphones
The goal of a PA system is to provide "public address", or
a way to transmit audio communication to a group. This
transmission can begin with a microphone, which is a
device that can assist in magnifying an audio source's
volume. A microphone is classified as a device that
transforms sound into an electrical signal. Microphones
used in PA systems are usually dynamic or condensers.
Dynamic microphones are more rugged than condensers
and are able to withstand the elements a little better.
Condenser microphones utilize their own power source
and produce better-quality audio signals, but can
sometimes be so sensitive that they also receive
background noises.

accessed 04/03/2013.
5. Mixers
If a microphone or another audio source is
used in a PA system, it is plugged into a mixer.
The mixer allows for multiple channels of
sound to be broadcast at different levels. This
can help prevent feedback if a PA system will
involve multiple microphones, instruments, or
other audio sources. For example, someone
may use a PA system to sing along with a pre-
recorded CD. The CD track could be plugged
into one channel, while the singer's voice
would be broadcast through another.

7. Amplifier
The amplifier is usually side by side or
incorporated with the mixer. The amplifier's job
is to magnify the audio signal by manipulating
its varying frequency qualities. Gain in an
amplifier refers to the decibel level of the
sound coming out of the speakers. Another
quality, Output Dynamic Range, refers to the
loud and soft levels of a specific channel's
sound. Too low of an output could result in
just broadcasting noise; too high of an output
can lead to distortion.

accessed 04/03/2013.
9. Loudspeakers
The loudspeaker is the output end of the PA
system, transforming the electrical signal back into
sound that a group can hear. A good loudspeaker
system will separate the differing sound frequencies
and broadcast them through different sound
channels for better quality output. Parts of a
loudspeaker system include a
woofer, which broadcasts low frequency sounds; and
tweeters, the drivers of high frequency output. Some
speakers also contain crossover systems that are
responsible for separating these
frequencies, reducing the electrical noise that can
sometimes accompany a PA system broadcast.

10. The Drivers
Drivers are the components that produce the sounds. They are
generally comprised of a coil of wire sitting within a magnetic field. As
electric current flows through the coil of wire it moves within the
magnetic field. By attaching a diaphram to the coil, we can make a
volume of air move at the same time and produce sound waves.
A single driver can be capable of producing the full range of audible
sounds. In practice, however, multiple drivers are more common in a
loudspeaker for efficiency reasons. A two-way system would have a
low-to-mid range frequency driver and a high-frequency driver too. One
of the reasons for separating these out is that high frequencies are
more directional. High frequency drivers are normally mounted along
with a horn in order to control the direction. If you take a look at the
specification for a loudspeaker, you should find a Dispersion property.
This indicates the angle at which the high frequencies leave the
loudspeaker. Narrower dispersion angles (30° - 60°) are more suited to
long-throw speaker applications whereas wider angles (90° - 100°) are
better for short-throw.

11. Crossovers
When a loudspeaker has more than one driver we need a way to split
the frequencies so that the low frequencies go to the low frequency
driver and the high frequencies to the high frequency driver, etc. This is
done using a Crossover.
A crossover splits an incoming audio signal into its component
frequency bands. Most two-way or three-way loudspeakers have an
inbuilt crossover network that does this job. This is known as a Passive
Crossover. More advanced systems use an external crossover known
as an Active Crossover. This works slightly differently as it is inserted
before the amplifier. In this case, you will require additional amplifier
channels to run each individual driver. This technique is referred to
as Bi-Amping. Such systems tend to sound cleaner, more detailed and
controlled with each driver being run by its own dedicated amplifier
channel. The down side is the expense as more amplifiers are required
as well as the active-crossover itself.

12. Impedance
We mentioned Impedance when we talked about amplifiers. This is a measure of the
Load that the speaker represents to the amplifier. It is measured in Ohms (W). Most
speakers have an Impedance of either 4W, 8W or 16W. This figure must be taken into
account when choosing the correct amplifier to use.
But what happens when you want to connect two or more loudspeakers to the same
amplifier channel? Does the impedance change? Well, yes it does, but not as you may
expect. When speakers are connected together they are connected in parallel. When
this happens the following maths applies:
To deal with more than two loads you just keep on adding terms to the right. So two
8W speakers would give a total of 4W and three 8W loads would give you a total load
of 2.67W. Be careful not to make the load too small. Most amplifiers have a minimum
load that they can drive, 2Wbeing the common minimum. Always check the
specifications of the equipment.

13. Cables & Connections
Cables, although among the cheapest
items in a PA, are very important. These
carry the audio signals between
components and should therefore be
chosen carefully in order to minimise
losses and interference which could
degrade the resulting sound.
