Bruel & Kjaer 4165 Highlights

  • High-quality conventional 1" condenser microphones, such as Brüel & Kj_r Types 4144 and 4145, and ½" diameter Types 4165 and 4166, provide for the majority of noise measurements to IEC, IS0 and ANSI standards
  • However, for measurements around the 20/1Pa reference pressure, a very low noise floor in the 1/3-octave bands between 20Hz and 20 kHz is needed
  • The microphone and preamplifier system, with a noise floor of typically -2,5dB(A), provides for this area without compromising the useful frequency range and omnidirectivity of a microphone intended for precision measurements
  • With narrow-band analysis, the noise floor falls to approximately -16dB for 1/3- octave bandwidth at 1 kHz, and -34dB for 3,16Hz bandwidth at 1 kHz
  • The system is thus well-suited to both laboratory and industrial applications ranging from hearing research to the measurement of very-low-level machine noise
