The document describes the analysis and design of a multi-purpose auditorium using STAAD.Pro v8i software. The auditorium will have a plinth area of 1900 sqm, seating capacity of 750, and height of 7.325m. It will be constructed using M30 grade concrete and Fe-500 steel. Bored cast-in-situ piles will be used for foundations. The STAAD model was generated and loads like dead, live, and wind loads were applied. Beams, columns, slabs, and foundations were designed to meet code requirements. Acoustic design considerations like reverberation time, echo reduction, and sound absorption were also addressed.

Stethoscopes are in use for more than 200 years for medical diagnostics, especially for auscultation in the healthcare domain. Recently, unprecedented growth in mobile technology has revived the use of stethoscopes for Telehealthcare. Digital or electronic stethoscopes are increasingly researched for use in Telehealthcare within the healthcare domain. Cardiovascular diseases have become highly prevalent worldwide, especially in the subcontinent. Improvements in diagnostics will improve the quality of life and prevent the loss of life. This research paper mainly focuses on the acoustical and multiphysics design aspects of the stethoscope for improved acoustical performance. A COMSOL model of the stethoscope chest piece was developed. The model was setup to investigate the effects of geometry, material of construction, noise and input pressure. The sound transmission efficiency of the components was investigated with multiphysics models by coupling the acoustical and structural performances. The effect of ambient noise on the performance was also studied and reported. This COMSOL model wasis further used to investigate the effects of shape, size and material parameters on the performance and improvement in the acoustic transmission and noise isolation. The frequency response of the system was also investigated for resonance and performance in relation to auscultation of cardio, lung and other sounds. Through this research paper the researchers share the initial findings for the development of acoustical and multiphysics design aspects of the stethoscope. The ultimate objective is to leverage the improvement in the acoustics of the stethoscope for use in Telehealthcare.
Humidity intrusion effects on the properties of sound acoustic of autoclaved ...eSAT Journals
Abstract Autoclaved Aerated Concrete (AAC) has been commonly known to exhibit favorable thermal properties, high fire resistance and high compressive resistance at relatively low density. However, little attention has been devoted to the sound insulation performance of AAC. One of the points needs to know is humidity intrusion effects on AAC members in areas with high relative humidity levels of Mediterranean climates which are important in durability and insulation properties of AAC. Tests on mechanical and physical properties of ACC carried out to study humidity intrusion effects on AAC members were studied with and w/o coatings on the surfaces. From the findings of this study, physical and mechanical autoclaved aerated concrete evaluated in three different humidity levels to compare the effect of humidity on properties of AAC. According to test results coating is the most important factor for improving resistivity of AAC walls, and these factors help AAC walls to keep their mechanical and physical properties against humidity. With its closed air pockets, AAC can provide very good sound insulation. This paper presents the results of studies on acoustic properties of AAC partitions aimed at identifying the effect of specific factors on AAC sound insulation performance.

2. ABSTRACT
An Auditorium is a room built to enable the audience to hear and watch various activities such as performing arts, conducting
cultural events, professing lectures, and carrying out various presentations and seminars. As it could be used for all the occasions
stated above it is called as Multi-purpose Auditorium.
This project deals with the “ANALYSIS & DESIGN OF AN MULTI-PURPOSE AUDITORIUM USING STAAD.Pro v8i”. The design will be
in confirmation with IS 456:2000 and SP16 for plain and reinforced concrete, IS:875-1987 Part 1,2,3 for Dead load, Live load and
Wind load calculations,IS:1893-2002 for Seismic loads and IS 2526:1963 for acoustic design.
The plinth area of the proposed Auditorium is 1900 Sq m with a Seating capacity of 750 Nos, height of the Auditorium will be at
two levels +4.35m and +7.325m. M30 Grade of concrete and Fe- 500 steel will be used for all VRCC (Vibro-Roller compacted
concrete) works. Bored cast-in-situ end bearing piles with M30 grade of concrete will be used for foundation works.

23. Acoustic Requirements
a) correct reverberation time,
b) absence of echo,
c) correct loudness level at all parts of the hall,
d) low background noise,
24. General Principles of Acoustic design
1) Site selection
Depending on ambient noise level
Background noise should not be more than 40-45 dB
2) Size and Shape
◦ in relation to the number of audience required to be seated.
◦ Avg height – 6 to 7.5 m, Fan shape is considered best, sidewalls shall not be
more than 100 degrees, Farthest seat shall not be more than 23 m with the
curtain line
3) Stage
Depends upon the type of Performance the hall is to cater for,
25. 4) Roof and ceiling
False ceiling, Sound proof material
Rear portion of ceiling is treated with sound absorbing material
5) Floor
Successive seats have to be raised over preceding ones, so that the listener head is about 12 cm above
the path of sound, which would pass over the head of the front person.
Angle of elevation of the inclined floor in auditorium should not exceed 8degrees
20% of the seating area should be allocated for lobby, Foyer
6) Seats
The angle subtended with the horizontal at the front most observer Should not exceed 30 degrees
Distance between the stage and front row should be 3.6m – 4.5m
Width of seat – 45- 56 cm
Distance between seats back to back – 85 - 106cm
7) Reverberation time :
Reverberation time is defined as the time it takes for an impulse of sound in a room to decay 60 dB, or
one millionth of the original level. This value is affected by most everything in the room, including room
volume, absorption of room materials, diffusion from surfaces, and room temperature and pressure
26. 8) Distribution of Acoustic Material
Those areas which cause objectionable sound reflection and need to be treated with sound absorbents
should be earmarked for treatment with sound absorbing material. These areas are
(a) the rear wall,
(b) the balcony parapet,
(c)any areas which may reflect sound back to the stage,
(d) concave areas
9) Sound Absorbing Materials
In an average hall, most of the absorption is provided by the audience. It is therefore, becomes desirable
to introduce special absorbers(such as wooden panelling) on ceilings and walls which will provide the
requisite amount of absorption so as to achieve optimum reverberation-time.
27. ADDITIONAL SCOPE
Carrying estimation and costing of the project
Scheduling of the project by brainstorming various activities and time required for each
activities
Managing construction phase using various project management tools like MS Project and
Primavera.
28. Conclusion
This project concerns the feasibility of construction of an auditorium with good
acoustic properties.
It involves the application of earlier coursework to carry out the analysis and
design of components of structure.
It was analysed using STAAD.Pro using generic loading, and AUTOCAD for
drawing and detailing the c/s and l/s of structural members.
The construction of auditorium presents a solution for many cultural
programmes being held.
