The test material consisted of sentences read by a man, with or without a picture representing as context one of the key words in each sentence. In Exper. I, 12 Ss (6M, 6F), inexperienced with lipreading, were presented test material in the audio-only (A), visual-only (V) and audio-visual (AV) modes. Speech signals were presented at 0 or -10 db S/N re a multitalker babble fixed at 60 dbA. The audio signal was delayed (re visual signal) in 6 steps from 0-300 msec. Exper. II repeated Exper. I with 6 Ss (2M, 4F) familiar with lipreading; the speech signal was presented at -5 db S/N and 4 audio delays from 0-240 msec. While these Ss performed better in the V mode than those in Exper. I, the main effects of context and delays were similar. The disruptive effect of the audio delay on speech perception with lipreading (AV mode) was a function of S/N, being relatively more disruptive at the worse S/N, but it was not significant for delays up to a range of 80-120 msec. The results are in agreement with the theory (McGrath and Summerfield, J. Acoust. Soc. Am., 1985, 77, 678-685) that sensitivity to audio-visual desynchrony is significant only at a syllabic level in connected speech. The results further imply that moderate delays of up to 80 msec introduced by speech-processing aids for lipreading, as for cochlear-implanted patients, will not interfere with the advantages of providing the auditory information.","PeriodicalId":76646,"journal":{"name":"The Journal of auditory research","volume":"26 1","pages":"27-41"},"PeriodicalIF":0.0,"publicationDate":"1986-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14731824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ss were also given the Stephens Oral Language Screening Test (SOLST), emphasizing syntactical development. Ss were then tested for verbal respeating of taped 5-word sentences and 5-word 1st-order sentential approximations at 32 db SL re SRT. Stimuli were presented at 0, 40, or 60% time compression (TC). Responses were scored right/wrong and also by Porch's multidimensional system involving repeats and cues. For both systems significant effects were obtained between a number of TC conditions vs both the LAC and SOLST. The LAC appeared to emphasize phonetic units, the SOLST linguistic units in real sentences. The TC condition appeared to emphasize linguistic units at both word and sentence levels, less so with increasing TC. Results supported the usefulness of the TC stimuli in assessing reading readiness and it was suggested that the various stimuli assess different aspects of auditory processing.","PeriodicalId":76646,"journal":{"name":"The Journal of auditory research","volume":"26 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"1986-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14731821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the R ear the tone was attenuated at 1 db/sec until it was inaudible. In the L ear the tone was attenuated at 5 db/sec, and S was asked to adjust the loudness in the L ear by pushing and releasing a hand-switch as in Bekesy audiometry in order to maintain so far as possible a binaural loudness match. At every reduction of 10 db in the R ear (i.e., every 10 sec) the SPL to the L ear was measured from the Bekesy-type tracing which yielded binaural loudness match. While there were inter-subject variations, for all Ss the level of the tone in the L ear (5 db/sec) had to be increased above physical equality for equal loudness, indicating the presence of more rapid adaptation in that ear. The disparity in 2 Ss progressed regularly from near zero after 10 sec to 16-17 db after 1 min. For 1 S, a constant disparity of about 6 db existed throughout the session. Binaural loudness balances by this descending method may be considered a manifestation of normal adaptation, confirming a previous report (Harbert and Young, J. Acoust. Soc. Am., 1968, 43, 752-756) for threshold differences produced by various attenuation rates at various suprathreshold starting levels. An analogous ascending procedure with 1 S yielded results susceptible to the same interpretation.","PeriodicalId":76646,"journal":{"name":"The Journal of auditory research","volume":"26 1","pages":"55-63"},"PeriodicalIF":0.0,"publicationDate":"1986-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14731718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Toward a standard for hearing conservation for underwater and hyperbaric environments.","authors":"P F Smith","doi":"","DOIUrl":"","url":null,"abstract":"Exposure of divers to intense noise in water is increasing, yet no general hearing-conservation standard for such exposures exists. This paper summarizes three theories of underwater hearing, the tympanic, bone-conduction, and dual path theories, and reviews empirical data in order to identify some requirements such a standard must meet. Among problems considered are hearing sensitivity in water, the frequency and dynamic ranges of the water-immersed ear, and non-auditory effects of underwater sound. It was concluded that no well-developed theoretical basis exists for extrapolating current hearing-conservation standards for air-borne noise to the underwater situation; the existing empirical evidence, except within the frequency range of 1.5-3.5 kc/s, is too scant to predict what levels of underwater noise would be safe for divers; the empirical data on underwater hearing suggest that the frequency range covered by an appropriate standard must be much broader, for both low and high frequencies, than is the case in air; in order to establish an appropriate standard, further research is required on the dynamic range of the ear in water; problems must be solved with shifts in the resonance frequency of the ear consequent to the introduction of helium-oxygen mixtures or other exotic gases and pressures during dry-helmet diving or during simulated underwater excursions in dry hyperbaric chambers; underwater noise exposure may involve hazards to other body systems than the ear; and some noise exposure conditions may interfere with job performance of divers.","PeriodicalId":76646,"journal":{"name":"The Journal of auditory research","volume":"25 4","pages":"221-38"},"PeriodicalIF":0.0,"publicationDate":"1985-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14996491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For pulsed tones of 250 msec (duty cycle 50%), thresholds were not significantly affected by attenuation rate/step size or by starting level. However, for continuous tones, increasing attenuation rate/step size yielded better thresholds for a given starting level. Decreasing starting level yielded better thresholds for a given attenuation rate/step size. Thus, deteriorated thresholds were yielded by the slower attenuations/step sizes and by the higher starting levels. These data may be explained as a manifestation of normal adaptation. The similar relative effects found here of attenuation rate/step size and of starting level, as compared to the data of an earlier study (Harbert and Young, 1968) which used the traditional up-down Bekesy method of threshold tracing lend support to the possible future clinical use of a descending-only technique.","PeriodicalId":76646,"journal":{"name":"The Journal of auditory research","volume":"25 4","pages":"201-8"},"PeriodicalIF":0.0,"publicationDate":"1985-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14958034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Scaling patient reports of hearing aid benefit.","authors":"C L Hutton, J A Canahl","doi":"","DOIUrl":"","url":null,"abstract":"Records of 743 adults seen for rehabilitation with amplification in 1978-82, were used to study the measurement properties of four widely used, single-item benefit scales. Patients in this sample displayed mild to severe adventitious losses and had been fitted with their first aid(s). Data relating to degree of hearing loss, age, and employment status were analyzed. Responses to Hutton's Hearing Problem Inventory (J. Acad. Rehab. Audiol., 1980, 13, 133-154), administered 6 weeks pre and post rehabilitation, were used to obtain estimates of benefit: hrs/day and portion of time aid(s) were worn, its benefit in various situations, and degree of satisfaction. From the HPI was abstracted a single index of perceived pre-post gain (PPPG). Matrix analyses separately for the employed and the unemployed pts isolating hearing loss and employment status revealed that when amount of hearing loss was the validity criterion, the employment groups differed only in hrs/day and portion of time worn, the employed group reporting a trend for more hrs/day of wear as hearing loss increased. When PPPG was the criterion, only one benefit index, dissatisfaction, did not increase with PPPG. Of 16 Spearman rank correlations between benefit indices and validity criteria, 6 were significant. The benefit scale of hrs/day of wear yielded 3, that for dissatisfaction, none. It was concluded that PPPG was the criterion best used to validate benefit scales as compared with the criteria of hearing loss or employment status.","PeriodicalId":76646,"journal":{"name":"The Journal of auditory research","volume":"25 4","pages":"255-69"},"PeriodicalIF":0.0,"publicationDate":"1985-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14958039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
