Acoustics

There are many proprietary acoustic products available, which of these statements is true?

The performance of products can vary significantly even though the products may appear to be similar
Acoustic vinyl flooring is good for impact sound because it addresses the issue at source
Standard office ceiling tiles help significantly with airborne sound insulation
Floor treatment systems all provide a similar improvement in sound insulation

Which of the following should be carried out for good detailing practice of junctions?

There should be continuous solid contact across separating walls and floors
Joints in lining boards should be staggered
Wall lining boards should be fitted in contact with the floor slab to minimise gaps
Avoid contact between wall and floor finishes

For separating floors between dwellings which of these statements are true?

Separating floors must include structural concrete
The ceiling part of the floor can have a significant effect on the acoustic performance
The floor treatment applied is usually insignificant to the acoustic performance
There is a wide range of separating floor solutions that can be used in steel framed buildings

3
4

Loudness of sound is measured in what units?

Hertz (Hz)
Joules (J)
Decibels (dB)
Watts (W)

For integration of elements which of these statements are correct?

It is necessary to consider the detailing for integration of elements to maintain acoustic performance
Only structural elements such as beams and columns are significant to sound insulation
Domestic scale pipes and electric cables are insignificant to sound insulation
Pipes and cables cannot be included in a domestic separating wall

Which of these statements is correct?

It is generally easier to provide sound insulation for high frequency sound
It is generally easier to provide sound insulation for low frequency sound
Sound insulation materials have the same effect on high frequency and low frequency sound
Sound insulation is only required for low frequency sound

Which of the following statements are true for acoustic design of hospitals?

Sound insulation between rooms is not an important design consideration

For demonstrating compliance with the acoustic regulations which of these statements is correct?

Robust Details must be used for construction of new dwellings
Dwellings must either be constructed using Robust Details or on-site acoustic testing must be carried out
A qualified acoustic engineer must assess the details used for constructing dwellings
All dwellings must undergo on-site acoustic testing
