2. Loudspeaker measurement - Wikipedia

   en.wikipedia.org/wiki/Loudspeaker_measurement

   Achieving truly realistic reproduction requires speakers capable of much higher levels than this, ideally around 130 dB SPL. Even though the level of live music measured on a (slow responding and RMS reading) sound level meter might be in the region of 100 dB SPL, programme level peaks on percussion will far exceed this. Most speakers give ...

3. Sound level meter - Wikipedia

   en.wikipedia.org/wiki/Sound_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. [ 1 ]

4. Audio system measurements - Wikipedia

   en.wikipedia.org/wiki/Audio_system_measurements

   The frequency range often specified for audio components is between 20 Hz to 20 kHz, which broadly reflects the human hearing range (the highest audible frequency for most people is less than 20 kHz, with 16 kHz being more typical [4]). Components with 'flat' frequency responses are often described as being linear.

5. Peak meter - Wikipedia

   en.wikipedia.org/wiki/Peak_meter

   A peak meter is a type of measuring instrument that visually indicates the instantaneous level of an audio signal that is passing through it (a sound level meter). In sound reproduction, the meter, whether peak or not, is usually meant to correspond to the perceived loudness of a particular signal. The term peak is used to denote the meter's ...

6. Peak programme meter - Wikipedia

   en.wikipedia.org/wiki/Peak_programme_meter

   A peak programme meter (PPM) is an instrument used in professional audio that indicates the level of an audio signal. Different kinds of PPM fall into broad categories: True peak programme meter. This shows the peak level of the waveform no matter how brief its duration. Quasi peak programme meter (QPPM). This only shows the true level of the ...
