The long‐term average speech spectrum (LTASS) and some dynamic characteristics of speech were determined for 12 languages: English (several dialects), Swedish, Danish, German, French (Canadian),…
The National Acoustic Laboratories' (NAL) New Procedure for Selecting the Gain and Frequency Response of a Hearing Aid
It is concluded that the new formula for selecting the gain and frequency response of a hearing aid should prescribe a near optimal frequency response with few exceptions.
Client Oriented Scale of Improvement (COSI) and its relationship to several other measures of benefit and satisfaction provided by hearing aids.
Several methods for measuring the self-reported benefit and satisfaction provided by a hearing aid were compared by administering all methods to each of 98 subjects, suggesting that most of the measures provide valid estimates of benefit and/or satisfaction.

A new procedure for fitting nonlinear hearing aids (National Acoustic Laboratories' nonlinear fitting procedure, version 1 [NAL-NL1]) is described. The rationale is to maximize speech intelligibility…
Development of the Listening in Spatialized Noise-Sentences Test (LISN-S)

- 1 April 2007
The LISN-S provides a quick, objective method of measuring a child's ability to understand speech in background noise, suggesting that binaural processing skills are still developing at age 5 yr.
Speech recognition of hearing-impaired listeners: predictions from audibility and the limited role of high-frequency amplification.
Results indicate that audibility cannot adequately explain speech recognition of many hearing-impaired listeners, and suggest that for people with severe or profound losses at the high frequencies, amplification should only achieve a low or zero sensation level at this region, contrary to the implications of the unmodified SII.

Binaural-Bimodal Fitting or Bilateral Implantation for Managing Severe to Profound Deafness: A Review

- 1 September 2007
The findings at 6 and 12 months after they received their second implant indicated that binaural function developed over time, and the extent of benefit depended on which abilities were assessed for the individual, as well as on which mode of bilateral stimulation with unilateral implantation.
