How does noise affect me?

Sound is emitted from thousands of everyday items and people all around us. Consistently loud or intermittent sounds can destroy your quality of life.

Frequency is also a factor with low frequency sounds being difficult to attenuate and high frequencies very effectively blocked. This is measured in Hertz – common noises are such as a stereo bass 40 – 80Hz, the human voice 300Hz, rock music peaking at 600 – 3000Hz (3kHz) and a chainsaw at 4kHz
