The acceptable noise level (ANL) is the maximum amount of background noise that listeners are willing to accept while listening to speech. ANL has not been studied in listeners who use languages other than English. The purpose of this study was to explore whether ANLs obtained from Korean listeners in both English and Korean were comparable to ANLs obtained from monolingual English listeners. The results showed that ANLs obtained in English (ANL-E) did not differ significantly for the bilingual and monolingual listeners. Additionally, a cross-language comparison, within bilinguals, showed that ANLs obtained using Korean (ANL-K) speech stimuli were not significantly different from ANL-E. Finally, speech perception in noise did not correlate with ANLs in English or Korean for the bilingual listeners. Results suggest that the ANL measure is language independent within bilinguals and may be of potential clinical use in minority language groups.Abbreviations: ANL = acceptance of noise level; ANL-E = acceptance of noise level in English; ANL-K = acceptance of noise level in Korean; BNL = background noise level; HP = high predictability; KSPIN = Korean speech perception in noise; L1 = first language; LP = low predictability; LPB = low proficiency bilingual in English; LTASS = Long-Term Average Speech Spectrum; MCL = most comfortable level; ME = monolingual English; MPB = moderate proficiency bilingual in English; R-SPIN = revised speech perception in noise; SNR = signalto-noise-ratio; SPIN = speech perception in noise Palabras Clave: Nivel aceptable de ruido, ruido de fondo, bilingüe, percepción del lenguaje Abreviaturas: ANL = nivel aceptable de ruido; ANL-E = aceptación del nivel de ruido en inglés; ANL-K = aceptación del nivel de ruido en coreano; BNL = nivel de ruido de fondo; HP = alta predictibilidad; KSPIN = Percepción del lenguaje en ruido en coreano; L1 = primera lengua; LP = baja predictibilidad; LPB = baja aptitud bilingüe en inglés; LTASS = Promedio a Largo Plazo del Espectro del Lenguaje; MCL = nivel más confortable; ME = inglés monolingüe; MPB = aptitud moderada bilingüe en inglés; R-SPIN = percepción del lenguaje en ruido-revisado; SNR = tasa señal/ruido; SPIN = percepción del lenguaje en ruido
Purpose: Vocalization development has not been studied thoroughly in infants with early-identified hearing loss who receive hearing aids in the 1 st year of life. This study sought to evaluate the relationship between auditory sensitivity and prelinguistic vocalization patterns in infants during the babbling stage. Method: Spontaneous vocalizations of 15 early-identified infants with varying degrees of hearing sensitivity, from normal to profound hearing loss, were audiotaped and perceptually transcribed. Associations between the infant's unaided pure-tone average and the following vocalizations were explored: canonical babbling ratio, percentage of utterances containing canonical syllables, canonical syllable shapes, number of syllable sequences, and consonant-onset patterns in canonical syllables. Results: Hearing sensitivity was significantly associated with the percentage of utterances containing canonical syllables, the vocalization types used in utterances, and canonical syllable shapes used by the infants. Conclusions: Auditory sensitivity contributes significantly to the emergence of babbling patterns. In addition, there is a need for continued study of the vocalizations of infants with milder forms of hearing loss, because in this study, their vocalizations were highly variable despite having received early amplification.
This tutorial provides a review of auditory research conducted with monolingual and bilingual speakers of Spanish and English. Based on a functional view of bilingualism and on auditory research findings showing that the bilingual experience may affect the outcome of auditory research, we discuss methods for improving descriptions of linguistically diverse research participants. The review delves into how the bilingual experience can affect auditory research outcomes and discusses ways in which experimental design can be adjusted when bilingual or monolingual participants are used for research needs. The goal of the tutorial is to increase awareness about the complexities of using bilinguals in auditory research, thereby improving the quality of auditory research involving bilingual research participants.
CI users with large ANLs reported more benefit from implants than those with small ANLs. The results of this preliminary study of ANL in CI users suggest that ANL can be used as a tool for evaluating processing in noise in individual CI users.
Although infants with hearing loss displayed a shorter looking time to speech compared to NH controls, HI infants nonetheless appear to have sufficient access to the speech signal to display a developmentally appropriate preference for IDS over ADS.
