Technical details
- Microphones:
- Pre-polarized ¼” pressure field microphones (G.R.A.S.): Dynamic range 38-168 dB, frequency range 4 Hz-70 kHz, applications up to 140°C.
- Pre-polarized ¼” free-field microphones (G.R.A.S.): Dynamic range 32 dB(A)-135 dB, frequency range 5 kHz-20 kHz.
- Various free-field and pressure-field microphones (1“, ½”, ¼") from Brüel & Kjær.
- Pressure sensors: Instationary sensors (Kulite) for various pressure ranges.
- Analysis devices: Sound level analyzer (Brüel & Kjær Type 2250), pistophones and calibrators.
- In-house developments:
- Acoustic camera for localization and analysis of sound sources.
- 2p impedance tube for the investigation of sound absorption materials.
