Thinklabs One electronic stethoscope addresses the specialized needs and unique challenges of hearing impaired medical professionals. Because One offers unparalled amplification, connectivity and adaptability, you can create a custom solution for auscultation that meets your individual needs. (Scroll down for more information on each style.)
1. Streamer connects to Thinklabs One via a cable included with the stethoscope.
2. If closed-fit provides an opening for some sound to enter the ear, headphone bass can transmit directly, which is helpful at low frequencies.
With a standard 3.5 mm jack, One connects to any headphones and because it has over 100x amplication, One is loud enough to compensate for hearing deficits. It will blow you away with maximum bass response - which is critical in listening to heart and lung sounds. Use One with headphones that offer strong bass; we like Beats Executive over-the-ear or Bose SoundTrue on-ear.
No Hearing Aids - Use One with your favorite audio headphones.
Earbuds, included with One, are lightweight and comfortable.
On-ear headphones fit onto the ear and provide a good seal.
Over-ear headphones have larger cups that completely cover the ear.
Open-fit hearing aids are mostly prescribed for high-frequency hearing loss and do not reproduce bass well. Therefore, they do not amplify low-frequency vibrations, like heart sounds. However, the open-fit style has the distinct advantage of allowing external sounds to travel directly to the eardrums, bypassing the hearing aids. You can therefore use headphones over your open-fit hearing aids. The One, driving good headphones, will produce excellent sound at a high volume, making it unlikely that you will need further amplification from your hearing aids for auscultation. Choose headphones that provide good bass. We don't recommend using a streamer with this type of hearing aid, as much of the audio will leak away from the open ear canal, making the hearing aids ineffective for bass reproduction.
Open-fit BTE Hearing Aids
Open-fit BTE with on-ear headphones - drive sound directly to eardrums, offers compact solution.
Open-fit BTE with over-ear headphones - drive sound directly to eardrums and cover hearing aids, reducing ambient sound.
Open-fit BTE with streamer - NOT Recommended - bass leaks out of open-fit.
Closed-fit hearing aids reproduce bass better than open-fit aids, but the sound depends on individual hearing loss, hearing aids, and whether the hearing aids are programmed for low-frequency reproduction. You can use headphones over closed-fit hearing aids or connect via a streamer. The closed fit requires that all sound to the eardrum goes through the hearing aid itself. The One, driving good headphones, will produce excellent sound at a high volume, which will then be picked up by the hearing aid recever, amplified and reproduced in the canal by the hearing aid speaker. Hence the dependence on hearing aid bass reproduction. To use a streamer, connect One via a cable that's provided by Thinklabs. The hearing aid is still required to reproduce the auscultation sounds. Many users find these solutions to be very effective. We recommend testing and fine tuning this solution with your audiologist.
Closed-fit BTE Hearing Aids
Closed-fit BTE with on-ear headphones - receiver-in-the-canal (RIC) picks up headphones sound, reproduced by hearing aid speaker. Program aids for strong bass.
Closed-fit BTE with over-ear headphones - same as on-ear but covers hearing aid and drives sound to top mic as well.
Closed-fit BTE w/Streamer - Connect One to your streamer via the cable we provide. See streamer section below.
ITC or CIC seal the auditory canal in the same way as Closed-fit BTEs discussed above. The same guidelines apply. (See Closed-fit BTE above.)
ITC, CIC Hearing Aids
ITC or CIC with on-ear headphones - receiver picks up headphones sound, reproduced by hearing aid speaker. Program aids for strong bass.
ITC or CIC with over-ear headphones - receiver picks up headphones sound, reproduced by hearing aid speaker. Program aids for strong bass.
