6Rxqg 3Uhvvxuh /Hyho 63; Maximum Sound Level (Spl) Capability - JBL Control 24C Application Manual

Single Speaker Coverage – The coverage area of a single speaker depends on the distance of the
speaker from the listener, which depends upon the ceiling height and the listening height (seated vs.
standing). The following chart assumes a 4 ft (1.2 m) listening plane and averages coverage over the
500 Hz to 8 kHz range:
10 Ft (3.1 m) Ceiling Height:
-6 dB coverage
14 Ft (4.3 m) Ceiling Height:
-6 dB coverage

Maximum Sound Level (SPL) Capability – In the simplest theoretical terms, loudspeakers are capable of
producing sound levels as determined by their sensitivity (the sound level they produce with one watt of
power) and their power handling capability (driven with an industry-standard pink noise signal) and the
distance the listening plane is from the speakers. This is NOT, however, a measure of the typical MUSIC
or SPEECH that can be expected from the system. Pink noise is different from music and speech. A
