We offer airborne sound insulation assessment where we reproduce audible airborne sound that could be transmitted from one residence, room or living quarters to another. Airborne sound insulation describes the insulation, between rooms separated by a wall or floor partition, of sound transmitted through air. The assessment results can be used to quantify, assess and compare the airborne sound insulation in unfurnished or furnished rooms. The measured airborne sound insulation is converted into a single number, the sound reduction index (SRI), to characterise the resistance to the passage of airborne sound between rooms.
Some standards that we use are
- ISO 16283-1:2014 Acoustics — Field measurement of sound insulation in buildings and of building elements — Part 1: Airborne sound insulation (replaces ISO 140-4:1998, ISO 140-5:1998,
ISO 140-7:1998, ISO 140-14:2004, ISO 140-14:2004/Cor 1:2007) - ISO 12999-1: 2014 Acoustics. Determination and application of measurement uncertainties in building acoustics. Part 1: Sound insulation.
- ISO 717-1:2020 Acoustics — Rating of sound insulation in buildings and of building elements — Part 1: Airborne sound insulation
- IEC 61260-1 Electroacoustics – Octave-band and fractional-octave-band filters – Part 2: Pattern-evaluation tests
- IEC 61672-1 Electroacoustics – Sound level meters – Part 1: Specifications
- ISO 3382-2:2008 Acoustics — Measurement of room acoustic parameters — Part 2: Reverberation time in ordinary rooms
