BRUEL & KJAER 2203 Instructions And Applications

response over the widest possible range and feature good temperature
stability and excellent long term stability. All free field microphones
have linear free field response for 0° incidence in the audio frequency
range. Pressure response microphones have linear response over the
widest possible range of frequencies.
The most important considerations in choosing a microphone are its
frequency response, sensitivity, and omnidirectivity. Generally, smaller
microphones give wider frequency range, better omnidirectivity, but
lower sensitivity. Small microphones are best suited for measurements
in intense sound fields, and also generate less turbulence at high wind
velocities.
6.2.4. Microphone Adaptor
UA 0030
UA 0030 permits mounting of the
half-inch microphone on Extension
Cable AO 0033 / 59. This adaptor
gives an attenuation of 0,1 dB.
6.2.5. Nose Cones
Fig. 6. 11. VA 0030
Nose Cones are available for all microphone sizes. Their characteris-
tics for reducing wind noise are given in the appropriate Microphone In-
struction Manual.
6.2.6. Extension Cables AO 0033/59
Extension Cable AO 0033 is 3 , meters (10ft) long and can be used to
remove the Microphone from the Sound Level Meter. Its attenuation is
approximately 0,1 dB with one-inch microphones and 0,3 dB with half-
inch microphones.
Extension Cable AO 0059 is similar to AO 0033 except it is 70 em
(27,5 in) long. Attenuation is approximately 0,05 dB with one-inch mi-
crophones and 0,2 dB with half-inch microphones.
