Description

4206 - A set of pipes for measurement of an impedance (50 Hz – 6.4 kHz)
4206 A - A set of pipes for measurement of an impedance (100 Hz – 3.2 kHz)
4206 T - A tube set for measurement of coefficient of losses on passing (50 Hz – 6.4 kHz)

Brüel &Kjær offers a full range of tubes for acoustic tests of materials, such as
measurement of coefficient of absorption of a sound, coefficient of reflection, an acoustic impedance and an admitans, and coefficient of losses on passing.

MISSION:

  • Description of properties of acoustic material
  • Verification of certain characteristics of material
  • Definition of entrance data for acoustic modeling
  • For the research purposes

FEATURES

  • The measurements based on a two-microphone method of transfer function in compliance with the international ISO 10534-2 and ASTM E1050-98 standards
  • Horizontal placement of the materials sensitive to orientation; modeling of measurements on false ceilings
  • It is mounted on a wall
  • Is part of full system of acoustic test of the materials Brüel& Kjær PULSE™
  • Determination of coefficient of noise reduction (ASTMC423-99a) on the basis of coefficients of absorption of a sound at 250, 500, 1000 and 2000 Hz (Type 4206 A)
