An international comparison of long‐term average speech spectra
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)
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.
Optimal Outcome Measures, Research Priorities, and International Cooperation
The participants in the Eriksholm Workshop on “Measuring Outcomes in Audiological Rehabilitation Using Hearing Aids” debated three issues that are reported in this article, including the concept of generating a brief universally applicable outcome measure.

Binaural-Bimodal Fitting or Bilateral Implantation for Managing Severe to Profound Deafness: A Review
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.
The NAL-NL2 Prescription Procedure
The data underlying Nal-NL2 and the derivation procedure are presented, and the main differences from NAL-NL1 are outlined.
