Acoustics
high, medium and low (HML)
Science; Acoustics
3-values related to the attenuation provided by hearing protectors at high, medium and low frequencies - supplied by the manufacturer.
statistical analysis
Science; Acoustics
A calculation performed by a sound level meter on the noise levels measured during the measurement period to describe the statistical levels Ln of the noise - more details.
milibars (mb)
Science; Acoustics
A common metric unit of atmospheric pressure, one hundredth of a bar. 1 mb = 0.001 bar = 100 Pa, pascals. A Pascal is one Newton per square meter.
watt second (WS)
Science; Acoustics
A common metric unit of work or energy, representing the energy delivered at a rate of 1 watt for a period of 1 second. 1 watt second = 1 J = 1 N·m
artificial voice
Science; Acoustics
A complex sound, usually emitted by an artificial mouth, whose spectrum corresponds to that of the average human voice.
