B & K Sound Intensity Calibrator — Type 3541

Description

Sound Intensity Calibrator — Type 3541 Include Sound Source ZI0055
USES:
❍ Sound intensity and particle velocity calibrations
❍ Sound pressure calibration
❍ Measurement of pressure-residual intensity index
FEATURES:
❍ Intensity coupler for simulating a plane sound wave
in a free field (US. pat. No. 4715219)
❍ Pistonphone for sound intensity, particle velocity
and sound pressure calibrations
❍ Broad-band sound source for pressure-residual
intensity index measurement
Type 3541 enables calibration of intensity
measuring instruments by using
a coupler designed especially for
sound intensity calibrations. Intensityprobe
microphones are positioned in
the coupler which, in conjunction with
a pistonphone, simulates a plane sound
wave propagating along the axis of the
probe. The instrument’s sensitivity to
both sound intensity and particle velocity
can then be calibrated. The pistonphone
can also be used for sound
pressure calibrations. In addition to
calibration, Type 3541 can be used to
measure the pressure-residual intensity
index spectrum of instruments used
for measuring sound intensity.
