Noise annoyance / stress

Noise Annoyance / Stress - Symptoms and Health Issues (see links)

Noise is “unwanted sound” and can be associated with annoyance and stress.  

 

"Noise can trigger both endocrine and autonomic nervous system responses that affect the cardiovascular system... These effects begin to be seen with long-term daily exposure to noise levels above 65 dB or with acute exposure to noise levels above 80 to 85 dB.... to place this in context, 85 dB is roughly equivalent to the noise of heavy truck traffic on a busy road."  Southern Medical Journal (excerpted from) WHO
