Sibelsound 400-A SCREENING AUDIOMETER - air conduction
The Sibelsound 400 is a two channels 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, etc).

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: Continuous, pulse, alternate, 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)
