The rate of emission of acoustical energy (i.e., sound power) of sources encountered in most noise control work is relatively small. Sound power usually is expressed in watts or in picowatts (millions of a millionth of a watt); 1 picowatt is equal to 10[upperscript -12]. The instantaneous power (the rate at which sound energy is radiated at any instant of time) fluctuates very considerably. 2, record 2, English, - instantaneous%20sound%20power

Speech Detection. If the Voice Activity Detector (VAD) option is active, a speech detector is used to identify periods of silence or idle VF channels to provide further compression in addition to ADPCM. This function is performed by the CDP card. The PCM signal is first passed through a high-pass filter to remove DC bias and 50/60 Hz. components that might disturb the speech or modem detectors. The energy of each sample is measured, and the average speech power is calculated. If the power is greater than -31 dBmO (dBmO equals a digital milliwatt), the signal is recognized as speech. This is a simplification of the VAD function. 2, record 3, English, - speech%20power
