SIBELSOUND 400-A SCREENING AUDIOMETER – air conduction
The SIBELSOUND 400 is a two-channel digital audiometer based on DSP processing. This audiometer is designed for quick and easy audiometric exploration of hearing thresholds and screening tests, such as suprathreshold pure tone tests (FOWLER-ABLB, TONE DECAY, WEBER, LUSCHER, …).
– Air conduction (TDH 39): 125 – 8,000 Hz or HF: 8,000-20,000 Hz with optional HDA 200
– Levels: AC (-10 to 120 dB HL) / BC (-10 to 70 dB HL) / speech (-10 to100 dB HL) free field (-10 to 80 dB HL)
– Masking levels (manual or synchronized): NBN AC (-10 to 100 dB HL) NBN BC (-10 to 70 dB HL) white & speech (-10 to 100 dB SPL)
– Tone: continous, pulse, anternate, amplitude modulation.
– Level increases: 5
– Frequency precision: ±1%/ level precision ±2% db SPL
– Automatic calculation of hearing loss and diagnosis (COUNCIL, IMSS MEXICO, ELI, SAL, KLOCKHOFF, MOH, OTHERS …)
– Direct USB connection to PC to W50 audiometry software for viewing, storage, transmission, analysis and introduction of audiometric tests (Windows® environment).
