The RT60 — Reverberation Analyser

The Klark Teknik RT60 is a dedicated reverberation-time analyser engineered for acousticians, system designers, and installation engineers who need accurate, defensible measurements of room decay characteristics across the audio spectrum. RT60 — the time taken for a signal to decay by 60 decibels — is the foundational metric of architectural acoustics, and Klark Teknik built an instrument to deliver that measurement to the precision the work demands.

Purpose-Built for Acoustic Measurement

The RT60 is engineered around the single discipline of accurate reverberation-time measurement — not a general analyser with RT60 as one feature, but an instrument purpose-built for the task. Frequency-band resolution, decay-rate calculation, and signal-handling are all optimised for the specific demands of room-acoustics work.

Field-Ready, Bench-Accurate

Built to Klark Teknik’s Kidderminster engineering standards, the RT60 holds its calibration in the conditions real measurement work imposes — concert halls, lecture theatres, sports arenas, and houses of worship are not bench environments. The RT60 was built to deliver bench accuracy in the field.

British Engineering, Acoustic Discipline

The RT60 reflects four decades of Klark Teknik measurement expertise, beginning with the DN60 in 1980 and continuing through every generation of professional analyser that has followed.
