80db.

Fill at least 2 decibel levels to calculate the total Sound level. Source1 dB. Source2 dB. Source3 dB. Add source +. Total SPL dB. A simple rule for adding up the sound levels is to assign a value between 0 – 3dB to the sound level caused by the loudest sound source. This value depends on the difference between two sound sources.

For every 3 dBAs over 85dBA, the permissible exposure time before possible damage can occur is …

It is a measure of the sound pressure level or loudness. The decibel scale is not a linear scale, it is a logarithmic scale. A doubling of your decibel reading does not mean a doubling of the noise—for every 10dB increase in sound our perception of loudness doubles. So 60dB is twice as loud as 50dB and 70dB is four times as loud as 50dB. ELECTROLUX Steam Iron E7SI1-80DB.

A signal-to-noise ratio compares a level of signal power to a level of noise power. It's most often expressed as a measurement of decibels (dB). Higher numbers generally mean a better specification since there's more useful information (the signal) than unwanted data (the noise). For example, when an audio component lists a signal-to-noise ...The Noise Regulations define 'exposure action values' – levels of noise exposure which, if exceeded, require you to take specific action. There are 'lower' and 'upper' action values. Lower exposure action value – daily or weekly personal noise exposure (LEP,d or LEP,w) of 80dB.
