3 ways to use the stethoscope
1. Wear headphones over your hearing aids
2. Plug the stethoscope into the audio input jack on your hearing aid Bluetooth accessory
3. Remove your hearing aids and use headphones or earbuds.
The compact design of Thinklabs One goes a long way towards addressing the needs of medical professionals with hearing loss. First, the ability to use headphones means that you can wear headphones over your hearing aids. We've solved the entire "have to remove my hearing aids" nuisance.
Second, One is loud. Really loud. Volume levels 0-5 are intended for those with normal hearing. Once you get into the 7-10 range, using good headphones, the volume becomes sufficiently loud that you can actually feel the low frequencies from the patient's heartbeat. In terms of dB amplification, it exceeds 100X a regular stethoscope.h
One is designed for high power output, with dedicated headphone amplifiers, one for each channel. Thinklabs' amplified stethoscope is the loudest stethoscope ever made and has fully adjustable volume (1-10) to fit the audio needs of any individual. Voltage doubling charge pumps provide extra headroom for low distortion reproduction of S1 and S2 heartbeat peaks. The headphone amplifiers have sufficient power to drive low-impedance audio headphones, producing 45.2mWatts (see Warning below). Competitive stethoscopes operate on lower voltage, use a single amplifier and high impedance speaker, resulting in clipped heartbeats at significantly lower power output.e
One uses materials and parts not usually found in stethoscopes:
High strength sapphire crystal, robust enough to be used in deep-sea chronometers
Precision-machined aluminum, hand-polished by people who work with satellite systems and other advanced applications requiring perfect finish
Specialized electronic components that are custom manufactured for Thinklabs
Gold-plated connectors and jacks to ensure low impedance connections
Design refinements that focus on minute, which achieve the last details of performance.
