Static pressure- and temperature coefficients of microphones

  • Rasmussen, Knud (Project Manager)

    Project Details


    The sensitivity of standard microphones depends on the environmental conditions. The basic theory has been developed and described, supported by experimental results in Metrologia vol 36, 1999, pp 265-273.
    The original measurement on microphones type B&K 4160 and 4180 has been repeated using a faster technique and a higher frequency resolution. As a result the static pressure- and temperature coefficients for these microphones can be described by a 9'th order polynomium rather than a table.
    In cooperation with Brüel & Kjær, the same technique will be used for determining these coefficients for selected types of Working Standard microphones.
