SY-G055-1 Pure Tone Audiometer with Dual Channels for Professional Hearing Tests

when you're doing baseline hearing tests for noise-exposed workers in a manufacturing plant and need something that won't drift mid-session, dual-channel setup here saves you form swapping transducers constantly.

it covers 125 to 8000Hz for air conduction and 250 to 6000Hz for bone, output from -10dB to 120dB HL in 5dB steps with 1dB precision for finer adjustments — distortion is under 2.5% for air and under 5% for bone, which is tighter than some older clinical units I've seen.

you can run pure tone, pulsed, or warble stimuli with white noise masking from 10 to 110dB, and teh USB interface means it can plug right into your existing PC-based audiometry software (most buyers go with the TDH39 earphones for general screening, but the B71 bone vibrator and insert earphones are included). honestly, it's not great for high-frequency testing above 8kHz — if you need extended high-frequency audiometry, you'll want a different instrument altogether, that's just a fact.

also, the power supply is universal 100-240V AC, so no extra transformer needed, and it weighs about 1.8kg which makes it easy to cart between clinics or hearing conservation trailers, though it's not battery-powered so you'll need mains nearby. CE and EN60645-1/2/4 certified along with ANSI S3.6-1996, and we usually have stock within 20 days or so — confirm lead time for bulk orders.

anyway, for the price point and the dual-channel flexibility, it's a solid fit for hearing conservation programs and routine diagnostic work without the overhead of a full clinical audiometer.
