Equipments Acoustics

Presentation

Programme (detailed contents):

Diffuse field, direct field

Different sound absorbers

Determination of absorption coefficient

Auditorium acoustics

Acoustic power of building services

Design methods

Objectives

At the end of this module, the student will have understood and be able to explain (main concepts):

- Diffusion of sound waves inside and outside rooms

- Transfer of acoustic waves along ductworks

- Transfer of vibrations generated by building services

The student will be able to:

- Calculate walls absorption to restrict noise dose absorption by workers

- Reduce noise propagation in ducts

- Define noise proof walls to protect the surrounding

- Size vibration pads

Needed prerequisite

Indoor building physics

Form of assessment

The evaluation of outcome prior learning is made as a continuous training during the semester. According ot the teaching, the assessment will be different: as a written exam, an oral exam, a record, a written report, peers review...
