High noise levels in offices and call centres is usually the result of staff talking too loudly.
Unlike noise in factories, which is covered by regulations for the protection of hearing, noise in offices does not usually cause such damage. The main problems here are with general irritation and making other communication difficult. Some of these problems can be dealt with to some extent by ensuring the room acoustics are good, or even using a noise masking system, such as white noise generators.
Reducing the noise at source us usually the best approach. A managed can ask people to quieten down, but this can cause embarrassment and bad feeling, and also depends on the manager's perception.
These office noise problems are best dealt with using a SoundEar Noise Warning Sign. Mounted on the wall at key positions, the SoundEar's mere presence will remind people to keep their voices down to a reasonable level. Should they forget, it lights up as a reminder, giving a very clear message.
