Keeping this in view, how can I monitor my noise level?
Noise is typically measured by adjusting how a human ear responds to sound (A or C weighted responses). A sound level meter (SLM) can measure sound at different frequencies (called octave band analysis) and record sound clips to determine the source of noise pollution.
