A sound level meter calibrator is a device that is used to calibrate sound level meters. This type of calibrator emits a known sound level at a specific frequency, and by adjusting the sound level meter to match this level, the accuracy of the meter can be ensured. There are a few different types of…

Sound Pressure Level Formula
Sound pressure level (SPL) is a logarithmic measure of the effective pressure of a sound wave. The sound pressure level is the square of the peak sound pressure divided by the root of the mean square pressure. The peak sound pressure is the maximum instantaneous pressure of the sound wave. The root of the mean…

The National Institute for Occupational Safety and Health (NIOSH) has released a new sound level meter app that allows users to measure the sound levels in their environment. The app, which is available for free download on the App Store and Google Play, can be used to measure sound levels in decibels (dB) and offers…
Read moreHow Is Sound Measured
How is sound measured? Sound is a vibration that propagates through an elastic medium, such as air or water, and is heard when it stimulates the auditory nerve. The human ear can hear sounds with frequencies from about 20 Hz to 20,000 Hz. The amplitude of a sound is the magnitude of its pressure fluctuations,…

Sound intensity is a measure of the amplitude of a sound wave. It is measured in decibels (dB), with higher values indicating a louder sound. The human ear can detect sounds with a wide range of intensities, from the faintest whispers to the loudest explosions. The threshold of human hearing is about 0 dB, while…
