The E-Scope Electronic Stethoscope, Model 718-7712 is designed for individuals with behind-the-ear (BTE) type hearing aids. The Stethoscope is used with one of the accessories found below. Includes accessory pack which contains: 1 pediatric diaphragm (white circle with silver frame) and 2 replacement membranes for diaphragm, 3 black pediatric and neonatal bells and 2 pair of eartips (one hard plastic and one mushroom style)

Hearing aids are designed for speech and generally have a low frequency in the 250 Hz range. Heart sounds, however, have a much lower frequency (20 Hz to 650 Hz). The first and second sound is approximately 70 Hz to 120 Hz and the third heart sound is approximately 50-60 Hz. Murmurs are generally in the 250-350 Hz range. Therefore, the hearing aid itself may be a limitation.

Hearing loss often occurs in the higher frequencies with lower frequencies still normal.

Method #1. In these cases, an ear mold may be the answer. This method has been quite successful. Then, use with the E-Scope Belt Model 718-7710 or 718-7750. These models are supplied with external headphones. The headphones are placed over the ear mold when using the E-Scope. This method bypasses the hearing aid and depends entirely upon the E-Scope for low frequency amplification.

Method #2. A direct audio input cable (for one ear Cardionics Model 711-7123 for two ears, Model 711-7125 can be connected from the E-Scope to the audio shoe (sometimes called a boot) of the hearing aid. Your audiologist will provide the audio shoe. The direct audio input cable (DAI) connects the Sounds output of the E-Scope to the audio shoe that in turn snaps on to the hearing aids.

Method #3. A silhouette (induction coil) can be connected to the E-Scope for one or both ears. The silhouette has worked well in many situations with BTE hearing aids. For one ear, useModel 711-7133 and for two ears, Model 711-7135. This is a small, flat plastic device that loops behind the ear between the BTE and the head and is worn only when using the stethoscope. Turn the BTE to the Telecoil position when using the silhouette cord (induction coil).

Method #4. The Cardionics large headphones Cardionics Model 718-0408 cover the entire ear and the BTE hearing aid. These have worked well in many cases. These headphones fold up for ease of carrying. They are somewhat bulky when not in use which is their major drawback.

As in all cases where hearing loss is involved, the audiologist can advise you as to the best solution for your situation.
