What is ISO 15186-3 - Sound insulation in buildings and of building elements using sound intensity about?
ISO 15186-3 is the third part of the multiple series that specifies a sound intensity method to determine the sound reduction index and the element normalized level difference of building elements at low frequencies. This method has significantly better reproducibility in a typical test facility than those of ISO 140-3, ISO 140-10, and ISO 15186-1. The results are more independent of the room dimensions of the laboratory and closer to values that would be measured between rooms of volume greater than 300 m3.
Note: ISO 15186-3 is applicable in the frequency range from 50 Hz to 160 Hz but is mainly intended for the frequency range from 50 Hz to 80 Hz.
Who is ISO 15186-3 - Sound insulation in buildings and of building elements using sound intensity for?
ISO 15186-3 on sound insulation in buildings and of building elements using sound intensity is useful for:
- Construction industries
- Civil engineers
- Designers
- Contractors
- Builders
- Testing laboratories of buildings
- Regulatory authorities
Why should you use ISO 15186-3 - Sound insulation in buildings and of building elements using sound intensity?
Measurement surface is the surface totally enclosing the test specimen on the receiving side, scanned or sampled by the probe during the measurements.
ISO 15186-3 specifies intensity measuring instrumentation that is capable of measuring intensity levels with reference to decibels in one-third-octave bands. ISO 15186-3 helps you to measure the average sound pressure level over the surface of the test specimen in the source room and the average sound intensity level on a measurement surface in the receiving room.
Overall, ISO 15186-3 assists you with measuring the sound reduction of the building and enhancing the quality and durability of the building.
