Buy or Rent RT60 Reverberation Time Measurement System
Complete system for measuring reverberation time (RT60: EDT, T20, T30) per DIN 18041 and ISO 3382—using a 2.5 kg chirp speaker instead of a heavy 15 kg dodecahedron.
- Chirp cross-correlation measures accurately down to 125 Hz even with running HVAC noise
- Only 2.5 kg total weight (active speaker + calibrated USB measurement mic + Akulap software)
- Automatic spatial averaging and instant DIN 18041 compliance report without Excel

With traditional interrupted pink noise, evaluating T30 requires at least 45 dB of signal-to-noise margin above ambient background noise. In an office or classroom with 50 dB of 125 Hz HVAC noise, this would require over 1,000 watts of amplifier power. Akulap's logarithmic sine sweep (chirp per ISO 18233) integrates energy over time: every doubling of sweep duration adds +6 dB of SNR, allowing our 2.5 kg active speaker to produce clean Schroeder decay curves even during normal building operation.
