Several studies show that noise has obvious impact on
occupant comfort and productivity (Tang S K, and C T, 1998). In an indoor
environment the main source of noise includes electrical equipments such as
television, Other outdoor factors can also influence indoor noise a great deal,
for example in busy towns traffic (automobiles, trains and planes) and
industrial noise can be a major factor when considering indoor noise.
Use a noise meter to establish if your indoor noise level is
within the acceptable tolerance. Noise is measured in decibels (dB). You might
just notice a 3 dB change in noise level, because of the way our ears work. Yet
every 3 dB doubles the noise, so what might seem like small differences in the
numbers can be quite significant.
When the noise level has been proven to be
problematic, there are several control techniques that can be employed, some
can be introduced quickly and cheaply with little or not effect on day to day
activities visit Health and Safety Executivefor more information.
