When taking on the acoustic conditioning of a room with acoustic panels made of sound-absorbent wood one needs to know what sound, noise and reverberation has to be dealt with.

In acoustic conditioning jobs, one can meet different acoustic situations and, depending on the types of noise present you will have to decide what acoustic panels and acoustic material is ideal to achieve the desired acoustic conditioning and/or insulation.

These are the types of noise that one can find, and that our expert in acoustics should assess and study before starting acoustic conditioning work:

.

–   Background noise: It is the noise that surrounds us, associated with the immediate environment which normally consists of different sounds from many sources that can be close by or further away.

–   Random noise: It is a fluctuating amount, whose instantaneous amplitudes appear as a function of time, according to a (Gaussian) distribution.

–   White noise: It is one that has an equal amount of energy across the entire frequency band, in other words, constant sound pressure levels over a wide range of frequencies.

–   Constant continuous noise: It is one whose average sound pressure level measured in octave bands does not fluctuate over time.

–   Constant intermittent noise: Like the previous one but fluctuating moderately over time.

–   Periodically fluctuating noise: It is similar to continuous noise but fluctuates periodically over time.

–   Non-periodic fluctuating noise: It is similar to the previous ones but with longer, non-periodic fluctuations.

–   Repetitive pulsating noise: It is a noise that comes in similar repeated pulses.

–   Simple pulsating noise: It is a noise that comes in isolated pulses.

–   Pink noise: It is the one in which all components provide the same subjective level, i.e. it is white noise but with a slope of –3 DB.
