Abstract
Method for conducting an on-site measurement of a density value of an insulation material is provided, comprising: (a) providing an acoustic source for emitting a sound wave; (b) directing the sound wave emitted from the acoustic source through a waveguide and at an insulation material present in a wall, floor or ceiling cavity; (c) measuring a sound pressure in the waveguide to obtain at least one sound pressure measurement; and (d) calculating a density value of the insulation material based on the at least one sound pressure measurement.

A method for conducting an on-site measurement of a density value of an insulation material, comprising:
- (a) providing an acoustic source for emitting a sound wave;
- (b) directing the sound wave emitted from the acoustic source through a waveguide and at an insulation material present in a wall, floor or ceiling cavity;
- (c) measuring a sound pressure in the waveguide to obtain at least one sound pressure measurement;
- and
- (d) calculating a density value of the insulation material based on the at least one sound pressure measurement.
A system for conducting an on-site measurement of a density value of an insulation material, comprising:
- an insulation material present in a wall, floor or ceiling cavity, and
- an acoustic source for emitting a sound wave, a waveguide for directing the sound wave at the insulation material present in a wall, floor or ceiling cavity, and at least one sound pressure sensor arranged to measure a sound pressure in the waveguide.
A system comprising:
- an insulation material present in a wall, floor or ceiling cavity,
- an acoustic source for emitting a sound wave,
- a waveguide for directing the sound wave at the insulation material present in the wall, floor or ceiling cavity, and
- at least one sound pressure sensor arranged to measure a sound pressure in the waveguide,
- wherein a surface of the wall, floor or ceiling cavity that faces the acoustic source is at least partially formed from a rigid acoustic reflecting material.
A system for conducting an on-site measurement of a density value of an insulation material, comprising:
- an acoustic source for emitting a Sound wave, a waveguide far directing the sound wave at an insulation material present in a wall, floor or ceiling cavity, and at least one sound pressure sensor arranged to measure a sound pressure in the waveguide, and
- a waveguide cap for attachment to the waveguide, wherein the waveguide cap is at least partially filled with a portion of the insulation material.
