Acoustics

The long-term focus of our laboratory is noise level and noise figure measurement, elec- troacoustic testing, building and room acoustics, sound power measurement and sound intensity mapping.

  • Sound frequency analysis.
  • Localization of sound sources with the help of acoustic intensity mapping.
  • Measurement of acoustic power.

Electroacoustics

  • Measurement of speaker parameters (according to CSN IEC 60268-5).
  • Sound system design and measurement.
  • Measurement of directional pattern.

Anechoic chamber

  • Complies with CSN EN ISO 3745 requirements.
  • Dimensions 5 x 4 x 6.4 m.
  • Low frequency limit 90 Hz.
  • Volume 128.3 m3.

Building acoustics

  • Measurement of transmission loss.
  • Noise sources mapping in buildings.
  • Reverberation time measurement.
