Sound level meter - Wikipedia

A sound level meter is used for acoustic (sound that travels through air) measurements. It is commonly a hand-held instrument with a microphone.The best type of microphone for sound level meters is the condenser microphone, which combines precision with stability and reliability.The diaphragm of the microphone responds to changes in air pressure caused by sound waves.

In practice, modern sound levels meters sample at more than ten times a second to improve the statistical accuracy if the sound levels fluctuate widely over time or are intermittent. Any statistical value between 0.01% and 99.99% may be calculated, but the widely used ones are the L10 and the L90 or L95. It is also good practice to state the period of time the measurements were taken over ...

This is often used to give an indication of the upper limit of fluctuating noise, such as that from road traffic. L50 is the noise level exceeded for 50% of the measurement duration. It is the middle point and ...

Air Conditioner Decibel Levels | Hunker

Basically, a 10-decibel differential equals a sound twice as loud as the sound 10 decibels lower. Noise at 60 decibels, which would be roughly the loudness of a loud window air conditioner, seems twice as loud as something at 50 decibels. To achieve this doubled sense of loudness, a sound 10 times more intense is required, which is why the doubling occurs every 10 decibels.

How To Calculate Sound Pressure & Sound Pressure Level

When people talk of sound level, they usually refer to it in decibels. This may be when thinking about OSHA requirements, how loud a rock band is, jet engines, or town ordinances. So what are decibels? To answer that, let us first look at sound pressure. Sound is measured by changes in air pressure. The louder a sound is, the larger the change in air pressure is. The change here is the change ...

Understanding & Measuring Digital Audio Levels

Audio signal or sound levels are measured using a decibel (dB) system. The dB system is used to compare two levels or a change in signal voltage or power. One dB is the level change that is just noticeable by most people. A 6 dB change is considered to be about twice the volume. Sound signal level in dB can be considered either as a power or as a voltage. The level in decibels is 10 times the ...
