“…Because the hearing aid microphone is turned off, the telecoil may substantially enhance the signalto-noise ratio (SNR) for the ear listening to the telephone. Although telecoils have been shown to provide some benefits relative to acoustic coupling (Cashman et al 1982;Sorri et al 2003), the benefit of induction loop or telecoil usage does not always yield superior speech recognition performance (Vargo et al 1970;Tannahill 1983;Holmes 1985).…”

Routing the signal to both hearing aids resulted in significantly better speech recognition than unilateral signal routing. Wireless signal routing was shown to be beneficial compared with acoustic telephone listening and in some conditions resulted in the best performance of all of the listening conditions evaluated. However, this advantage was only evident when the signal was routed to both ears and when hearing aid wearers were fitted with occluding domes. Therefore, it is expected that the benefits of this new wireless streaming technology over existing telephone coupling methods will be most evident clinically in hearing aid wearers who require more limited venting than is typically used in open canal fittings.

In some cases, lack of telecoil benefit may have been related to suboptimal frequency shaping of the telecoil response (Hodgson and Sung, 1972;Rodriguez et al, 1993).…”

For people with moderate-to-severe sensorineural hearing loss, acoustic telephone listening with a hearing aid may not lead to acceptable performance in noise. Although unilateral routing options (telecoil and wireless streaming) improved performance, speech recognition performance and subjective ratings of ease and comfort were best when bilateral wireless routing was used. These results suggest that wireless routing is a potentially beneficial telephone listening strategy for listeners with moderate-to-severe hearing loss who are fitted with limited venting if the telephone signal is routed to both ears. Unilateral wireless routing may provide similar benefits to traditional unilateral telecoil. However, the newer wireless systems may have the advantage for some listeners in that they do not include some of the positioning constraints associated with telecoil use.

“…10%, according to a 2003 report by Sorri et al 20 Regardless of their severity, hearing problems can place a considerable strain on interpersonal relationships, as they usually make communication more difficult and affect social interactions. 21 Indeed, unacknowledged or unaddressed hearing loss has been associated with a 52% increase in the incidence of social isolation among 60-to 69-year-old Americans.…”

How Successful is the Fitting of Digital Hearing Aids? Implications for the Allocation of Resources within National Health Systems

We conducted a retrospective study to determine the success rate of initial fittings in digital hearing aid (DHA) users. We also addressed the implications of national health systems' continuing to provide access to these devices. We identified 1,597 consecutively presenting adults who had undergone a first fitting or a new fitting (i.e., an upgrade from an analogue hearing aid in the first or second ear) of a behind-the-ear DHA during the previous year. We further sought to identify all nominal reprogram appointments that had taken place within 6 months after the first or new fitting; we found 460 such appointments (28.8%). Of these, 419 appointments had been for typical reasons other than patient dissatisfaction with the fitting itself-for example, poor hearing, a further hearing loss, an uncomfortably loud hearing aid level, difficulty with speech in noise, an imbalance between bilateral hearing aids, and a faulty or lost hearing aid. Only 41 of the 1,597 first or new fittings (2.6%) were considered unsatisfactory by patients and necessitated a follow-up reprogramming appointment. Overall, DHA fittings were generally successful, as most patients (1,137/1,597 [71.2%]) did not require any follow-up appointment during the study period. Principles of cost-effectiveness demand the maximum practicable efficiency in the utilization of resources to ensure the continuous delivery of high-quality audiologic services through national health systems. This can be achieved by scheduling group appointments to reduce costs and to increase the time allocated to fitting and training patients.
