How valid is it to make a sound measurement in direct flow of air? I am not surprised that blowing air directly in to sound measurement device causes high reading, but is the tool designed for that. Isn't it the same as saying that pressure washer causes x decibels of noise when directed in to ear? Both will probably be damaging or unpleasant.
- fwip 7y agoShe measured sound levels at the ear, not in the airflow. She specifically mentions children being shorter and likely to stand closer to the noise source, and so made readings at multiple distances.
