The latest standards for sound insulation requirements for communication base stations

What's new in the sound transmission & insulation in buildings Handbook?

Help is here! We’ve updated our Sound Transmission and Insulation in Buildings handbook to align with NCC 2022. This handbook expands on the regulatory requirements of the NCC in Volumes One and Two. It provides design guidance for practitioners to consider when implementing solutions to provide acceptable levels of sound insulation.

What are the performance requirements for sound transmission and insulation?

The Performance Requirements for sound transmission and insulation are now quantified in NCC Volume One and Two. This means the Performance Requirements now primarily include numerical targets that clarify the level of performance required, rather than qualitative (non-numerical) statements.

Can a building withstand a sound insulation test?

The sound insulation performance of the entire building cannot. This is because laboratory tests are not subject to the same site conditions as building elements installed in the field (refer to Appendix D and ‘field test’). Noise reduction coefficient (NRC): A measure of the ability of a material to absorb sound.

What is the difference between sound insulation and sound transmission class?

Sound insulation: Sound Insulation refers to the ability of a construction or building element to limit sound transmission through the building element. The sound insulation of a material can be described by the RW or DnT,w of the system. Sound Transmission Class (STC): A measure of the sound insulation performance of a building element.

Can sound insulation performance be measured in a laboratory?

Laboratory test: The sound insulation performance of a building element can be accurately measured in a laboratory. The sound insulation performance of the entire building cannot. This is because laboratory tests are not subject to the same site conditions as building elements installed in the field (refer to Appendix D and ‘field test’).

Does the IBC have acoustic requirements for non-residential buildings?

The IBC does not have acoustic requirements for non-residential buildings. The IBC is a model code, which means it is up to each jurisdiction to set and enforce its own codes specific to the needs of its region using the IBC as the guide. OSHA sound exposure limits
