The E-Scope II is an amplified stethoscope that is available in a stand-alone version (i.e. for non-hearing instrument wearers) and in several modified models specifically designed to interface with hearing instruments. The modified versions of the E-Scope II will look exactly like the stand-alone model with the exception that the earpieces of the modified version will be completely removed; in lieu of earpieces, a pair of headphones or other connection cable including a DAI, silhouette, and/or patch cord cables may be used to interface with hearing instruments.
Beyond choosing an appropriate modified E-Scope model, audiologists must take the following into consideration for their hearing instrument wearing patients. First, the most critical lung (breath) sounds for differential diagnosis will fall in the 200-600 Hz range; the most critical heart sounds will fall in the 70-120 Hz range. Since these are very low frequency sounds, regardless of audiometric configuration, you should provide a low-frequency emphasis program with the hearing instrument adjusted with the low frequency range set as low as possible (i.e. 100-250Hz). Second, lung and heart sounds are extremely soft sounds; in the case of patients with normal low frequency hearing, go ahead and manipulate compression ratios to 2:1 or even 3:1 in the low frequencies to see if these settings will enable your patient to better hear these soft sounds. Finally, remember that there isn’t a one-size-fits-all solution. For more information, check out the free-to-view webinar on amplified stethoscope solutions at AudiologyOnline.
