Fundamentals

Acoustics - Design process

Many stages of the testing process affect the acoustic performance of the building, from design right through to proactive maintenance. 

Acoustics - Noise categories

Any moving or vibrating parts in a product can produce noise; this varies with the operation of the product.

Acoustics - Noise rating

Different products can have an identical noise rating (NR), but be audibly different.

Acoustics - Octave bands

The amount and frequency distribution of the total noise is determined by measuring it with an octave band analyser.

Acoustics - Sound definition

Sound power cannot be measured directly, but the small fluctuations in the air pressure can be, expressed in Pascals (Pa).

Frequency

Providing information for each frequency band means that noise migration solutions can be tailored to individual products.
