Technology / Home Audio / Loudness: The Sound Pressure Level of a standard sound which appears to be as loud as the unknown. Loudness level is measured in phons and equals the equivalent SPL in db of the standard. [For example, a sound judged as loud as a 40 db-SPL 1 khz tone has a loudness level of 40 phons. Also, it takes 10 phons (an increase of 10 db-SPL) to be judged twice as loud.]

Loudness Compensation

Technology / Home Audio / Loudness Compensation: When played quietly, this switched circuit allows fuller apparent sound from a system such that the tendancy for human hearing sensitivity to drop off at certain frequencies is compensated and the ful MORE
