The AC40 Clinical Audiometer is a dual-channel clinical audiometer produced by Interacoustics (Denmark), which is widely used in the field of hearing diagnosis.
The following is a detailed introduction:
- Device Category: Class II medical device.
- Structural Composition: Consists of a main unit (signal source, power amplifier, signal level controller), electroacoustic transducers (air-conduction headphones, bone-conduction headphones), and a patient response device.
- Application Scope: Used for measuring human auditory thresholds and providing a basis for diagnosing auditory disorders.
- Flexible Operation Modes: Supports standalone operation, computer-based operation, and integration with systems such as NOAH for data management and sharing.
- Clear Display: Equipped with an 8.4-inch large color display screen that can clearly show a large amount of test information. It also offers multiple display options, allowing customized readings based on personal preferences.
- Diversified Testing Functions: Features various functions including high-frequency testing, tinnitus matching, and binaural masking level difference (MLD) testing. It supports multifrequency audiometry, Stenger pure tone testing, speech testing, and automatic threshold testing, meeting diverse needs in clinical practice and research.
- Large Storage Capacity: Can store 1,000 patient profiles and 50,000 test results. Test results can be retrieved from internal memory or displayed online on a computer.
- Rich Interfaces: Equipped with an HDMI interface, which can be connected to an external large screen to facilitate communication between doctors and patients and the display of test results.
- Frequency Range: 125 Hz - 8 kHz; optional high-frequency testing function is available, with a maximum frequency of up to 20 kHz.
- Maximum Output: 120 dB HL for air conduction, 80 dB HL for bone conduction.
- Attenuation Step: 1 dB + 5 dB.
- Masking Types: Including narrowband noise (NB), wideband noise (WN), speech noise (SN), pink noise (PN), etc.
