Purpose of this study:

To determine improvement in the reliability of ratings obtained with a field evaluation unit by comparing ratings grouped by environment vs. ratings grouped by acoustics of the environment.

Project Description:

The improvement in the reliability of ratings obtained with a field evaluation unit will be determined by comparing ratings grouped by the category of the environment vs. ratings grouped by the acoustics of the environment. Participants will be 15 normal hearing participants. Participants will rate passages of recordings obtained in the field using two test procedures, (1) paper/pencil ratings that include a verbal descriptor of the situation rated, and (2) ratings using the field evaluation unit. Both test procedures will be carried out in each of two test sessions. Order of testing will be counterbalanced within and between participants. Within each test session, ten ratings on each of four dimensions of speech quality (speech intelligibility, loudness, noisiness, pleasantness) will be obtained with each method.
