What Are The Different Sound Sources Found In Marquees?
- Live Music
- Recorded Music
- Construction Noise
- People Noise
Characteristics of Sound
Sound can be characterised by two primary variables, frequency and amplitude. The frequency defines the cycle rate of the waveform and therefore the type of sound we hear i.e. low frequency (bass), high frequency (treble), or anything in between.
Amplitude defines the loudness of the sound i.e. it is quiet or loud. Both of these characteristics will affect (a) how far the sound travels and (b) how much is absorbed by an acoustic barrier.
What Is The Local Environment?
Noise can be simply defined as any unwanted sound i.e. one man’s music, is another man’s noise. Taking personal preference out of the equation – noise pollution is therefore the impact that a sound source has upon the ambient noise level, bearing in mind that ambient noise levels vary between urban/rural, day/night etc.
Once the source, time and environment have been identified we are able to either measure or estimate it’s characteristics based on previous experience. In some instances it is possible to reduce the sound source itself, this should always be prioritised as in turn it reduces the amount of energy we need to contain.
