RESULTS AND DISCUSSION F igure 1 presents a long-term spectral analy-sis of the two sets of speech materials WebMasking Level Difference (MLD) testing has become an important addition to clinical audiology test batteries. Although data are available relating the MLD to a variety of pathological conditions, little information exists dealing with learning disabled individuals. This study presents normative MLD data for a population of 90 learning disabled individuals.

WebPure-tone threshold audiometry is the measurement of an individual's hearing sensitivity for calibrated pure tones. Three general methods are used: (a) manual audiometry, also referred to as conventional audiometry; (b) automatic audiometry, also known as Békésy audiometry; and (c) computerized audiometry. gems in the rough contest 2022WebThe American Speech-Hearing-Language Association (ASHA) Guidelines for Manual Pure-Tone Threshold Audiometry contain procedures for accomplishing hearing threshold … gems in the dunesgems in the rough contest 2023Web4 de jun. de 1998 · Slopes of functions relating consonant recognition to masker spectrum level were similar within subject pairs, whereas, in some cases, slopes of functions relating consonant recognition to speech level were shallower for hearing‐impaired subjects than for their normal‐hearing counterparts. gems in the beryl familyWebPure tones, however, ...
