FAQ for Audiometer NADM-100
1: Why does the Audiometer NADM-100 offer different frequency ranges for air and bone conduction testing?
The Audiometer NADM-100 is designed with distinct frequency ranges to accurately assess various parts of the auditory system. Air conduction covers 125 to 8000 Hz to evaluate overall hearing, while bone conduction (250 to 6000 Hz) targets inner ear function specifically.
2: How does the response switch input enhance operation of the Audiometer NADM-100?
The response switch input on the Audiometer NADM-100 enables patients to indicate when they hear a sound, allowing smoother test flow and more accurate response tracking during hearing assessments.
3: Is the Audiometer NADM-100 capable of performing masked hearing tests?
Yes, the Audiometer NADM-100 includes narrowband noise masking, which is essential for conducting ear-specific tests and preventing sound crossover between ears.
4: What should I check if the Audiometer NADM-100 produces uneven sound levels?
If the Audiometer NADM-100 delivers inconsistent sound, check earphone placement, balance the sound settings, inspect connections, and ensure the attenuator is functioning properly at its 5 dB step size.
5: What is the role of the response indicator light on the Audiometer NADM-100?
The response indicator light on the Audiometer NADM-100 provides a clear visual confirmation of patient input, reducing communication errors and improving test reliability.
6: How does the sound intensity extension function enhance this audiometer's usability?
The sound intensity extension function in this audiometer allows controlled increases in sound output levels without compromising patient comfort or test accuracy. It helps audiologists evaluate individuals with varying degrees of hearing loss, including those with reduced sensitivity, by providing extended intensity options within safe and standardized limits.
7: Can the audiometer store or transmit hearing test data for patient records?
Yes, the audiometer supports data transmission, making it easier to manage, store, and retrieve patient test results. This functionality streamlines clinical workflows by enabling digital recordkeeping and reduces the chances of manual errors, especially in high-volume screening environments.
8: What is the purpose of the response switch input on this audiometer?
Our audiometer includes a response switch input that allows the patient to indicate when they hear a sound during testing. This feature improves the accuracy of hearing threshold detection, ensures active participation from the test subject, and enhances the efficiency of the overall assessment process.
9: What features of this audiometer contribute to high-precision hearing assessment
The audiometer includes a dual-row LCD display for clear visibility, a high-precision output control button for fine adjustments, and a built-in response indicator light. Additionally, it uses narrowband noise masking to minimize interference during testing. These features work together to ensure accurate, repeatable, and clinically reliable results.
