Listed below are typical sound pressure levels (SPLs) for various types of music. The SPL meter was set to C-weighting, slow response. You might want your system to be at least 10 dB above the background noise level to achieve a good signal-to-noise ratio. New age: 60-70 dB Folk: 75-90 dB Jazz: 80-95 dB Classical: 100 dB Pop: 90-95 dB Rock: 95

• The Noise level of a system sets the lower limit on the magnitude of a signal that can be detected in the presence of the noise. So, to achieve the best performance you need to have a minimum residual noise level. • Noise Figure is used to describe the noise contribution of a device. An ideal amplifier

A dB is unit used to measure the power of a signal, such as an electrical signal or sound, relative to some reference level. An increase of ten decibels in the power of a signal is equivalent to increasing its power by a factor of ten. As a measure of sound intensity, a zero-decibel (0 dB), reference is considered to be the lowest level audible to the human ear; the speaking voice of most

Signal-to-noise ratio (SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise.SNR is defined as the ratio of signal power to the noise power, often expressed in decibels.A ratio higher than 1:1 (greater than 0 dB) indicates more signal than noise.

A noise level chart showing examples of sounds with dB levels ranging from 0 to 180 decibels. Most noise levels are given in dBA, which are decibels adjusted to reflect the ear's response to different frequencies of sound. Sudden, brief impulse sounds, like many of those shown at 120 dB or greater, are often given in dB (no adjustment).

Recent NIOSH studies of sound levels from weapons fires have shown that they may range from a low of 144 dB SPL for small caliber weapons such as a 0.22 caliber rifle to as high as a 172 dB SPL for a 0.357 caliber revolver. Double ear protection is recommended for shooters, combining soft, insertable earplugs and external ear muffs.
