Room Acoustics Reverberation Time Measurement

This test method specifies procedures for measuring reverberation time and other room acoustic parameters in ordinary rooms such as offices, classrooms, lecture halls, and residential spaces. Reverberation time (T30 or T20) is a fundamental acoustic property that affects speech intelligibility, sound quality, and acoustic comfort. It is essential for designing spaces with appropriate acoustic characteristics, verifying construction specifications, and ensuring compliance with building standards. Architects, acousticians, and building professionals rely on these measurements to evaluate and optimize room acoustic performance. ISO 17025 accreditation guarantees accurate measurements following standardized methodology.

What it measures

  • Reverberation time (T30, T20, EDT)
  • Frequency-dependent acoustic absorption
  • Early decay time and room acoustic parameters
  • Clarity index (C50) and definition (D50)
  • Speech transmission index (STI) indicators
