  • How much noise does it makes m1911

    Sound is measured in decibels (db) much like temperature is measured in degrees and speed in miles (or kilometers) per hour. Like most other units the bottom of the scale or 0 db is an arbitrary setting which by convention is set to be the level of the sound that we can bearly hear or our hearing threshold as it is normally known.

  • Negative health impact of noise from industrial wind

    Nov 12 2014 · Annoyance from turbine noise at 35 dBA corresponds to the annoyance reported for other common community-noise sources at 45 dBA. The World Health Organization (WHO) has concluded that observable effects of nighttime outdoor noise levels of 40 dBA or higher will lead to diminished health.This also occurs when levels inside homes (especially bedrooms) rise above 30

    Noise is present in many workplaces but being exposed to too much can cause permanent and irreversible damage to workers. Noise levels and the duration of the worker s exposure to noise should be reduced. Loud machines and equipment are among the most common causes of harm to workers hearing.
