CanteenIn this recording the sound was drowned out because the canteen was noisy so the recording also picked up background noise for example conversations, canteen staff working and a slight humming noise coming from the vending machines. Some electrical equipment can cause interference for example mobile phones which can cause a ticking noise when sending or receiving electronic messages. Also the wooden chairs have absorbed the sound wear as the metal tables have reflected it.

In this environment the wooden chairs and the wooden floor

adsorb the sound

The metal tables and chair legs reflect the sound and

In the background there are a lot of conversations going so

the sound is drowned out by the noise and is also deadened by

people.

There are also vending machines in the

background which are creating a ‘humming’ noise which is also heard on the

recording.
