spl (sound pressure level): a measurement of the volume of sound, expressed in decibels (db): a function of amplitude.
sensitivity: the sound pressure level directly in front of the speaker (on axis) at a given distance and produced by a given amount of power.
shield: a metal enclosure that prevents electronic components from being affected by unwanted interference. shielded speakers may be placed near a tv, for instance, because their magnets cannot affect the picture tube.
shelving: the setting of the on-axis output of complementary drivers (woofers, mid-range, tweeters) to provide the desired frequency response.
sibilance: a hissing sound produced when pronouncing s and z. sibilance is undesirable in professional sound reinforcement and can be controlled through the use of a de-esser like valley 乐鱼官网在线登录
’s 401 microphone processor, 815 dynamic sibilance processor, or 730 dynamap digital dynamics processor.
signal: an electrical impulse.
signal-to-noise-ratio: the ratio, expressed in db, of an electronic device’s nominal output to its noise floor.
snake: a cable – often running between the stage and control board – that combines multiple lines; used to connect mics, instruments and monitors to a mixer.
sound level meter: a device that measures, in db, the amplitude of sound waves.
sound pressure level (spl): the measurement of the loudness, or amplitude, of sound, expressed in db.
sound reinforcement: the use of electronic devices to reinforce, alter or increase the level of sound.
spider: an internal speaker component whose function is to precisely position the voice coil in relation to a gap in the motor.
splowt : a unit of measure, expressed as db, that divides a speaker’s maximum spl by its weight in pounds. 2022世界杯附加赛决赛
’s micro spot boasts a splowt of 43 db (highest in the known universe).
supercool: to cool (a liquid) below a transition temperature without the transition occurring, especially to cool below the freezing point without solidification.
