Best Care Experience
## **Every Patient Deserves a Test They Can Trust**
At Auditdata, we believe great hearing care starts with great measurement. That means transducers that perform consistently from the first patient of the day to the last — because your clinicians shouldn't have to second-guess their tools.
The BC1 was designed around the realities of a working audiology clinic: busy schedules, diverse patient populations, and zero tolerance for unreliable results. It integrates seamlessly with the Auditdata Measure ecosystem, giving you one connected workflow from test to fitting.
- **Consistent results, every session**. Stable performance aligned with calibration standards means audiologists can focus on the patient, not the equipment.
- **Designed for real clinical workflows**. 2.5m cable length, broad headband compatibility (BCHB1), and multiple plug options adapt to your setup — not the other way around.
- **Confidence backed by certification**. Full Class 2a Medical Device certification ensures your compliance obligations are met without extra work.
The transducers demonstrated stable and consistent performance aligned with clinical and industry expectations — evaluated under simulated real-clinic conditions using professional audiometric calibration procedures and equipment.

WHAT WE CLAIM
## **Every Claim, Backed By Data**
The BC1 is built to perform to specification — here's exactly what that means.
**High-quality audio performance** specifically designed for hearing loss testing, not a general-purpose transducer repurposed for audiometry.
**Output Sound Level Precision of ±3 dB** controlled accuracy across the full −10 to 80 dB HL range, at time of manufacturing.
**Total Harmonic Distortion below 5.5%** at 25 dB HL @ 250 Hz across 500 Hz–4kHz, maintaining signal integrity where it matters most.
**Sensitivity of 96 dB VFL at 1 kHz, 1 mW** verified at time of manufacturing for reliable, repeatable output.
**Biocompatible per ISO 10993-1** lead, nickel, and latex free; RoHS compatible. Safe for direct patient contact.
**Standardised headband pressure of 5.4 N (±0.5 N)** ensuring consistent placement across patients for reproducible bone conduction measurements.
**Compatible with BCHB1 Real Ear headband** (new 2026) designed for the Auditdata Measure ecosystem for a fully integrated workflow.
**Available in multiple plug formats**; DIN, Mini-DIN (8-pin Green), Mono Jack, Mono Mini-Jack for broad equipment compatibility.
Technical Datasheet
## **BC1 Specifications**
**What the BC1 bone conductor is designed for:** The BC1 is designed exclusively for audiological hearing loss measurements, specifically pure-tone bone conduction audiometry in the 250 to 4,000 Hz range. It delivers an output range of −10 to 80 dB HL with ±3 dB precision at the time of manufacturing, making it suitable for diagnostic-grade pure-tone threshold testing in clinical settings.

**Frequently Asked Questions**
## What frequency range does the Auditdata BC1 bone conductor cover?
The BC1 covers 250 Hz to 4,000 Hz, the standard bone conduction range for pure-tone audiometry as defined by IEC 60645-1:2017 and ANSI S3.6:2018. Maximum output levels range from 45 dB HL at 250 Hz to 75 dB HL at 1,000–3,000 Hz.
## Is the BC1 compatible with all audiometers?
The BC1 is on request available with multiple plug options on DIN, Mini-DIN, Mono Jack, and Mono Mini-Jack, making it compatible with most clinical audiometers. It is natively supported on the Auditdata Measure 2000-1 via the 8-pin Green Mini-DIN connector (Part No. 100.060).
## What certification does the BC1 bone conductor have?
The BC1 is a Class 2a Medical Device meeting IEC 60645-1:2017 and ANSI S3.6:2018 (R2023). It is biocompatible per ISO 10993-1 and is free from lead, nickel, and latex. It is also RoHS compatible.
## Who validated the new bone conductor (BC1)?
The BC1 was independently evaluated by Audiometrix, Austrian-based audiology experts, under simulated real-clinic conditions. The evaluation confirmed stable and consistent audio performance aligned with clinical and industry expectations for audiometric bone conduction testing.
## What headbands are compatible with the BC1?
The BC1 supports the BCHB1 Real Ear headband (introduced 2026). Headband pressure is standardised at 5.4 N (±0.5 N) for consistent placement across patients.
## Can spare parts be ordered for the BC1?
Yes. Padding, headband, and cable are all available as individual spare parts, enabling repair and refurbishment of the BC1 rather than full replacement reducing equipment cost over the lifecycle.
