Children can only develop spoken language through consistent exposure to the acoustic cues that comprise speech and language. Until recently, hearing levels from the clinical audiogram were the primary measure used to define typical hearing and the presence or degree of a child's hearing loss. While the clinical audiogram remains an important…

Purpose: The goal of this study was to determine the ability of the AzBio speech recognition in noise (SRN) test to distinguish between groups of participants with and without a self-reported SRN disorder and a self-reported signal-to-noise ratio (SNR) loss. Method: Fifty-four native English-speaking young adults with normal pure-tone thresholds…

Purpose: Audiology clinics have a need for a nonlinguistic test for assessing speech scores for patients using hearing aids or cochlear implants. One such test, the Spectral-Temporally Modulated Ripple Test Lite for computeRless Measurement (SLRM), has been developed for use in clinics, but it, as well as the related Spectral-Temporally Modulated…

Purpose: This study investigated methods used to simulate factors associated with reduced audibility, increased speech levels, and spectral shaping for aided older adults with hearing loss. Simulations provided to younger normal-hearing adults were used to investigate the effect of sensation level, speech presentation level, and spectral shape in…

Purpose: Music training has been proposed as a possible tool for auditory training in older adults, as it may improve both auditory and cognitive skills. However, the evidence to support such benefits is mixed. The goal of this study was to determine the differential effects of lifelong musical training and working memory on speech recognition in…

Purpose: This study sought to evaluate the effects of common hearing aid microphone technologies on speech recognition and listening effort, and to evaluate potential predictive factors related to microphone benefits for school-age children with hearing loss in a realistic listening situation. Method: Children (n = 17, ages 10-17 years) with…

Purpose: General language abilities of children with cochlear implants have been thoroughly investigated, especially at young ages, but far less is known about how well they process language in real-world settings, especially in higher grades. This study addressed this gap in knowledge by examining recognition of sentences with complex syntactic…

Purpose: This study aimed to evaluate the effects of aging and cochlear implant (CI) on psychoacoustic and speech recognition abilities and to assess the relative contributions of psychoacoustic and demographic factors to speech recognition of older CI (OCI) users. Method: Twelve OCI users, 12 older acoustic-hearing (OAH) listeners age-matched to…

The type, degree, and configuration of hearing loss, if one is present, can be determined by reading an audiogram. The type of hearing loss is determined by comparing auditory thresholds obtained using head-phones or insert earphones (air-conduction thresholds) to those obtained using a bone oscillator (bone-conduction thresholds). By itself, the…

Purpose: To determine the rankings of 6 input-output functions for understanding low-level, conversational, and high-level speech in multitalker babble without manipulating volume control for listeners with normal hearing, flat sensorineural hearing loss, and mildly sloping sensorineural hearing loss. Method: Peak clipping, compression limiting,…

Purpose: The contribution of audible high-frequency information to speech-understanding performance in listeners with varying degrees of high-frequency sensorineural hearing loss was examined. Method: Thirty-six elderly hearing-impaired (EHI) and 24 young normal-hearing (YNH) listeners were tested in quiet (+20 dB speech-to-noise ratio [SNR]) and…

Purpose: To examine age-related differences in auditory speech recognition and visual text recognition performance for parallel sets of stimulus materials in the auditory and visual modalities. In addition, the effects of variation in rate of presentation of stimuli in each modality were investigated in each age group. Method: A mixed-model design…

A two-microphone adaptive digital noise cancellation technique improved word-recognition ability for 20 normal and 12 hearing-impaired adults by reducing multitalker speech babble and speech spectrum noise 18-22 dB. Word recognition improvements averaged 37-50 percent for normal and 27-40 percent for hearing-impaired subjects. Improvement was best…

The Speech Reception Test was developed to measure an individual's ability to hear and understand conversational speech. The equipment used to record the test is described in detail, and data are given for the results of the test given to 100 normal-hearing college students. Other data describe the results for 55 military veterans with known…

The Communications Aids Lab at the National Technical Institute for the Deaf was designed for training the hearing impaired to participate in various telephone communication situations through the use of special equipment and learned strategies of communication. Approximately 44% of the students, having non-functional hearing and unintelligible…
