Loudspeaker measurement is the practice of determining the behaviour of loudspeakers by measuring various aspects of performance. This measurement is especially important because loudspeakers, being transducers, have a higher level of distortion than other audio system components used in playback or sound reinforcement.
Audio CDs use a bit depth of 16-bits, while DVD-Video and Blu-ray discs can use 24-bit audio. The maximum dynamic range of a 16-bit system is about 96 dB, [ 10 ] while for 24 bit it is about 144 dB.
WSB-TV (channel 2) is a television station in Atlanta, Georgia, United States, affiliated with ABC.It is the flagship television property of locally based Cox Media Group, which has owned the station since its inception, and is sister to radio stations WSB (750 AM), WSBB-FM (95.5), WSRV (97.1 FM), WSB-FM (98.5) and WALR-FM (104.1).
If you've been shopping in a big box retail store you've probably heard an announcement on the loudspeaker such as, "code yellow toys, code yellow toys." This "code" is one of many innocuous ...
A loudspeaker (commonly referred to as a speaker or, more fully, a speaker system) is a combination of one or more speaker drivers, an enclosure, and electrical connections (possibly including a crossover network). The speaker driver is an electroacoustic transducer [1]: 597 that converts an electrical audio signal into a corresponding sound. [2]
Typical loads used are 8 and 4 ohms per channel; many amplifiers used in professional audio are also specified at 2 ohms. Considerably more power can be delivered if distortion is allowed to increase; some manufacturers quote maximum power at a higher distortion, like 10%, making their equipment appear more powerful than if measured at an ...
The 1925 paper [1] of Chester W. Rice and Edward W. Kellogg, fueled by advances in radio and electronics, increased interest in direct radiator loudspeakers. In 1930, A. J. Thuras of Bell Labs patented (US Patent No. 1869178) his "Sound Translating Device" (essentially a vented box) which was evidence of the interest in many types of enclosure design at the time.
South Korea will begin loudspeaker broadcasts directed at North Korea on Sunday that will be "unbearable" for the Kim Jong Un regime, its National Security Council said, after Pyongyang resumed ...
