The ADC Adscope 658 Electronic Stethoscope offers exceptional amplification compared to a traditional acoustic stethoscope. Each one features a contact-activated microphone that filters higher-frequency background noises. Sounds that typically interfere with auscultation, such as thick clothing, are drowned out and replaced with amplified heart and lung sounds. The bi-lumen (dual channel) cardiology headset optimizes the acoustic pathway. This stethoscope is designed with heavy-walled tubing, large-diameter aural tubes and a double-leaf tensioning spring that withstands thousands of cycles.
