How to solve your loudspeaker testing problems

The weakest link in your measurement chain is your chamber, the new TTC chambers solve these problems...

  • Anechoic chambers have massive footprints:
    The TTC gives you equal or better results with a compact footprint
  • Achieving repeatable measurements is difficult in an anechoic chamber:
    The TTC guarantees the microphone and loudspeaker positions
  • Anechoic chamber accuracy suffers at low frequencies:
    The TTC is capable of measuring below 20 Hz
  • Results are not transferable between most test chambers:
    The TTC meets international standards IEC 60268-21:2018 & IEC 60268-22:2020
  • Most chambers are difficult to calibrate and awkward to use:
    The TTC is calibrated and is ready to interface to your microphone and analyzer

The TTC establishes a new normal for R&D and production line loudspeaker testing

After an exhaustive peer review the concept has been included as part of IEC 60268-21:2018 & IEC 60268-22:2020, and AES73id-2019.

The TTC delivers results better than +/-0.5dB 20Hz to 20kHz to a 95% confidence level.

Repeatable results

  • Results typically repeatable within +/-0.25dB (20-20kHz)
  • Controlled distance between the loudspeaker and the measurement microphone
  • Tetrahedral shape eliminates standing waves ensuring consistent low frequency response

Accurate results

  • Fixed environment which guarantees the measurement accuracy
  • Controlled pressure and high frequency environment ensure accurate wideband frequency response (20-20kHz)

Transferrable results

  • Tetrahedral structure and calibration of the TTC ensures transferrable results between chambers
  • Meets IEC 60268-21-2018, IEC 60268-22 ED1, and AES 73id-2019 standards
