RMS (Root mean square) is a measure of the continuous power required by a device, in particular audio amplifiers and loudspeakers.

The effective resistance of an electric circuit or component to alternating current, arising from the combined effects of ohmic resistance and reactance.

Total harmonic distortion is a measure of non-linear harmonicdistortion and is given in %. Non-linear harmonic distortions aresignals which were not present in the original before the signal wasconverted by the headphones. These unwanted signals are caused by thediaphragm, whose movements do not precisely move in time with theelectric signals that cause it to move. Unfortunately, this is afeature of all electroacoustic transducers. Although it cannot becompletely eliminated, suitable steps can be taken to minimise it.However, the user is not interested in why this distortion takes placebut in how great the level of distortion must be for it to becomeperceptible. According to the findings of several research projects, atotal harmonic distortion of 1% in the frequency range of 100 to 2000Hz is imperceptible. Below 100 Hz, the perceptibility threshold liesat 10%.

Type of loudspeaker enclosure that uses the sound from the rear side of the diaphragm to increase the efficiency of the system at low frequencies as compared to a typical closed box loudspeaker or an infinite baffle mounting.

Form of entertainment in which people take turns to sing popular songs into a microphone over pre-recorded backing tracks.
