Overview

Proposed method improves reverberation time measurement in building acoustics, suggesting wireless speakers may enhance accuracy.

Key Points

  • To propose an alternative method for measuring reverberation time using compact wireless loudspeakers.
  • Developed a small wireless loudspeaker to reproduce short sine-swept pulses via Bluetooth.
  • Evaluated the performance in a reverberation room by comparing results to a reference method.
  • Considered sweep properties including pulse length, sweep rate, and harmonic distortion.
  • Achieved high signal-to-noise ratios using the wireless loudspeaker.
  • Reverberation time measurements were highly consistent with reference method results.
