B-weighted sound pressure level is written either as dB B or L B, and C-weighted sound pressure level is written either as dB C or L C.
42.
The ATL design enables the speakers to produce higher sound pressure levels and deeper bass extension than is possible with similar sized speakers using either sealed cabinets.
43.
B-weighted sound pressure level is written either as dB B or L B, and C-weighted sound pressure level is written either as dB C or L C.
44.
The minimum audible change in sound pressure level is generally thought to be around 1 dB, but less than 0.1 dB has been reported in blind listening tests.
45.
The Speech Interference Level is calculated as the arithmetic mean of unweighted sound pressure levels in three or four octave bands in the 500 Hz-4 kHz frequency range
46.
As another indicator, a night-time average sound pressure level of 55 decibel increased the risk of heart attacks by 66 % in men and 139 % in women.
47.
The associated flame trench need not be so sturdy as with a vertical test stand, however a water system may be less effective at reducing the sound pressure level.
48.
Sound pressure levels can go up to 150 dBSPL . Acoustic tests are used to verify the mechanical resistance of the satellite and its elements to acoustic pressures generated.
49.
The artist and title are written as " MAZK SPL " on the disc and " Masami Akita & Zbigniew Karkowski Sound Pressure Level " on the insert.
50.
These drivers can easily be stacked vertically, building a high frequency line array that produces high sound pressure levels much farther away from the speaker locations than do conventional tweeters.
