IEC 60601-2-37 Medical Ultrasound Human Perception Safety Testing
The IEC 60601-2-37 standard is a critical component in the safety testing of medical ultrasound devices. This international standard ensures that these devices are safe and do not cause discomfort or harm to patients during use, particularly regarding their human perception aspects. The standard covers requirements for psychoacoustics and human perception testing, which are crucial when evaluating the auditory effects of certain ultrasound frequencies on humans.
Medical ultrasound devices emit high-frequency sound waves that interact with tissues in the body. These interactions can generate audible noise, which can be perceived by patients during procedures. The IEC 60601-2-37 test ensures that this noise is within safe limits to prevent discomfort or potential harm to patients. This testing focuses on several key areas including sound pressure levels, frequency ranges, and the duration of exposure.
The process involves exposing subjects to controlled ultrasound emissions while measuring their auditory responses. The standard specifies exact parameters for these tests, such as the permissible sound pressure level (SPL) at various frequencies. For instance, it sets out that the SPL should not exceed 120 dB at any frequency, especially in critical areas like the ears.
The testing procedure is designed to be rigorous and precise. It involves detailed preparation of the test environment, including isolation from external noise sources and ensuring consistent temperature and humidity levels. The subjects are carefully selected based on their hearing health and ability to respond accurately to auditory stimuli. During the test, they are exposed to ultrasound emissions while wearing headphones that capture their responses.
The results are meticulously recorded and analyzed using advanced signal processing techniques. Compliance with IEC 60601-2-37 ensures that medical devices meet stringent international safety standards. This not only protects patients but also enhances the reputation of manufacturers who adhere to these rigorous protocols. The testing process is continuous, requiring periodic re-evaluation as technology and patient care practices evolve.
The importance of this test cannot be overstated in the field of medical ultrasound equipment. It ensures that devices are safe for use by a wide range of patients, including those with sensitive hearing or other auditory conditions. Compliance with IEC 60601-2-37 is mandatory for manufacturers seeking CE marking, which is essential for marketing their products within Europe and beyond.
In summary, the IEC 60601-2-37 test is a vital part of ensuring that medical ultrasound devices are safe and do not cause discomfort or harm to patients. This testing process involves precise measurements and detailed subject evaluations, ensuring compliance with international standards for patient safety.

Use Cases and Application Examples
The IEC 60601-2-37 standard applies to a wide range of medical ultrasound devices, including diagnostic systems used by radiologists and cardiologists. These devices emit high-frequency sound waves that can generate audible noise during use. The psychoacoustics and human perception testing specified in this standard ensures that these emissions are safe for patients.
One common application is in obstetric ultrasounds, where expectant mothers undergo regular scans to monitor fetal development. Ensuring compliance with IEC 60601-2-37 is crucial here because the noise generated by these devices can potentially affect maternal comfort and even fetal well-being if not controlled.
In cardiac catheterization labs, ultrasound-guided procedures are performed to diagnose heart conditions. The equipment used in these labs must adhere strictly to IEC 60601-2-37 to ensure that the emitted noise does not cause discomfort or distress to patients undergoing such procedures.
Neurology departments also use ultrasound devices for various diagnostic purposes, including transcranial Doppler studies. These tests require careful adherence to safety standards like IEC 60601-2-37 to ensure that the auditory effects on patients are minimal and safe.
In addition to diagnostic uses, medical ultrasound devices are also employed in therapeutic applications such as lithotripsy for kidney stone treatment and ultrasound-guided biopsies. In these scenarios, patient comfort is paramount, and IEC 60601-2-37 ensures that the emitted noise does not cause discomfort or harm.
The standard’s application extends to various types of ultrasound devices, including portable units used in emergency rooms and mobile clinics. These devices need to meet stringent safety standards to ensure they are safe for use by both patients and medical staff in diverse environments.
