Transmission Loss (TL) is a tool for measuring the insulating properties of walls, floors, or doors separating two rooms. It is based several international standards, including ISO 140-4, "Acoustics - Measurement of sound insulation in buildings and of building elements", ISO 717-1. "Acoustics - Rating of sound insulation in buildings and of building elements - Part 1: Airborne sound insulation", ASTM E336, "Standard Test Method for Measurement of Airborne Sound Attenuation between Rooms in Buildings", and also ASTM E-90 for Transmission Loss (TL), E413-87 for Sound Transmission Class (STC), and E1332-90 for Outdoor-Indoor Transmission Class (OITC).
- Measure sending and receiving room 1/3 octave levels, and also measure reverb time (RT) and ambient noise in the receiving room, if desired
- Everything is computed automatically and the results appear in a professional-looking graph ready to export and add to your reports
- Refer to the specifications that apply in your use to case to determine what to analyze
- More information about setting up and performing the tests to meet the appropriate standards
- Depending on the results that you require, you may not need to measure the RT time using the room reverb module
