Spl level meter
A sound level meter (also called sound pressure level meter (SPL)) is used for acoustic 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 A and C weightings are thus most meaningful for describing the frequency response of the human ear toward real world sounds. As acoustic sound level measurements are often motivated by the effect of sounds on humans, the A-weighting filter is commonly applied. The C-weighting filter is often applied when representing peak levels.

When the dial is set to 70, the needle is displaying sound pressure measurement relative to 70. When the needle hits the middle 0 position, the SPL of the sound you’re measuring is 70dB. If it reads -4, that means it is 4 under 70, or 66dB. Sep 22, 2013 ... Just like many other qualities of sound, loudness is subjective. It's relative, and changes according to person to person.

The SPL, measured in Decibels (dB), has been widely used since the 1930s. SPL is defined as the logarithm of the ratio of the sound pressure to a reference pressure. SPL = 20 log10(p/pref) dB. p → the instantaneous sound pressure in Pa. flights to seattle from atlantamalecon housebajar pelis gratis For this reason, the decibel meter is also known as a sound pressure level (SPL) meter.
