Artificial Ear Type 4153 enables accurate headphone testing and audiometer calibration under controlled acoustic conditions for reliable, reproducible results.
Artificial Ear Type 4153
Artificial Ear Type 4153 is a precision electroacoustic measurement device designed for audiometry and related acoustic testing applications.
It provides well-defined and repeatable acoustic conditions for testing headphones and insert earphones, enabling accurate comparison of product designs and highly reproducible measurement results.
Compliant with IEC 60318-1 standards, Type 4153 simulates the acoustic impedance of the human ear, making it a reliable platform for standardized electroacoustic measurements and audiometer calibration.
Its rugged design combines a precision acoustic coupler, microphone mounting capability, and an adjustable clamping system that helps ensure consistent positioning and contact force during testing.
Vibration-isolating rubber feet further support measurement stability and repeatability.
Artificial Ear Type 4153 enables electroacoustic measurements of headphones and insert earphones under controlled and standardized conditions.
Its acoustic coupler incorporates three interconnected volumes that reproduce the acoustic characteristics required by IEC standards, allowing measurements that closely represent real-world ear loading.
When combined with a compatible pressure-field microphone, the system can be used to evaluate frequency response, sensitivity, and other key performance parameters.
A supplied high-acoustic-impedance sound source supports calibration activities, helping maintain measurement accuracy and traceability.
Type 4153 is designed for seamless integration into professional electroacoustic measurement setups.
It accommodates ½-inch pressure-field microphones and can be used with compatible microphone preamplifiers mounted directly in the housing or via supplied adapter rings.
The artificial ear is delivered with adapters that support a variety of headphone and earphone test configurations, including circumaural headphones.
Its adjustable clamping mechanism allows users to apply standardized forces in accordance with relevant ANSI requirements, while the included calibration source simplifies verification of system performance.
These features make Type 4153 an effective component within laboratory, production, and compliance-testing environments.
Artificial Ear: a standardized acoustic device that simulates the acoustic properties of the human ear, allowing headphones, earphones, and hearing-related devices to be tested under repeatable conditions.
Acoustic Impedance: the opposition that an acoustic system presents to sound transmission. Matching human-ear acoustic impedance helps ensure that measurements reflect realistic operating conditions.
Pressure-Field Microphone: a precision measurement microphone designed to accurately measure sound pressure in enclosed or controlled acoustic environments. In Type 4153, it serves as the reference sensor for electroacoustic measurements.
Electroacoustic Measurement: the process of evaluating how electrical signals are converted into sound and vice versa, including measurements such as frequency response, sensitivity, and calibration performance.
