The Effects of Signal Processing and Style on Perceived Value of Hearing Aids |
| |
by Harvey Abrams, PhD; Michael Block, PhD; and Theresa Hnath Chisolm, PhD |
| |
A study using computer-simulated scenarios that assessed consumers’ willingness to pay (WTP) for four advanced features suggests that feedback cancellation and directional microphones were valued more than expansion and noise management. For individuals with no hearing aid experience, WTP values systematically decreased as the hearing aid size increased. |

The Reliability of Aided Sound-field Thresholds in Nonlinear Hearing Aids |
| |
by Francis Kuk, PhD; Denise Keenan, MA; Chi-chuen Lau, PhD; and Carl Ludvigsen, MS |
| |
A modulated sinusoid that is 1-2 seconds in duration—when coupled with sufficiently long and randomly spaced interstimulus intervals—is sufficient to achieve reliable aided sound-field threshold results in most non-linear hearing aids. Here’s how to measure ASFTs in your practice. |
