Phrases in noise test (PINT) Brazil: effectiveness of the test in children with hearing loss

IntroductionOne of the main implications of hearing impairment is the difficulty in perceiving speech sounds, especially in noisy environments. Thus, the frequency-modulated system is considered an important educational tool for children with hearing impairment because it improves speech perception in acoustically-unfavorable environments, such as in the classroom. The assessment of speech perception in noise is included in the verification protocol of this device.ObjectivesTo verify the effectiveness of the phrases in noise test Brazil in children with hearing impairment using an frequency-modulated system.MethodsThis was a cross-sectional cohort study. The sample included 40 children, aged 4 years to 11 years and 11 months old, divided into 4 groups: (1) 10 normal hearing children; (2) 13 children with hearing aids and frequency-modulated system; (3) 12 children using cochlear implant and fitted with the frequency-modulated system; and (4) 5 children diagnosed with auditory neuropathy spectrum disorder, fitted with hearing aids and/or cochlear implant and with the frequency-modulated system. The phrases in noise test Brazil was used to evaluate speech perception in noise under the conditions with and without the frequency-modulated system. For the statistical analysis of the data, a significance level of 5% (p < 0.05) was adopted.ResultsThere was a significant difference between the groups when they were evaluated with the frequency-modulated system. The test was also validated through concurrent and convergent validation measures. Phrases in noise test Brazil is a viable option for monitoring auditory performance in noise in different groups of children with hearing impairmen.ConclusionPhrases in noise test Brazil was effective in assessing speech perception in noise and may contribute to the improvement of the indication, fitting and follow-up protocols for the frequency-modulated system use.

Learning effect observed for the speech reception threshold in interrupted noise with normal hearing listeners

Traditionally, the speech reception threshold (SRT) for sentences in noise is measured in stationary speech-shaped noise; however, non-stationary masking noises are gradually becoming more common. A previous study by Rhebergen et al. () suggested that a learning effect might be present for the SRT in interrupted noise but not in stationary noise. The current study tested if a stable SRT for female or male speech is reached by determining SRTs in listeners with normal hearing in either stationary or 8-Hz interrupted noise after five replications. Contrary to repeated SRT measurements in stationary noise, a significant improvement was observed for SRTs in interrupted noise with replication. For both speech materials, after five replications, the SRT in interrupted noise improved about 3 to 4 dB in comparison to the first SRT. Stable thresholds seem to be reached after about two replications. This experiment shows that there is a substantial learning effect present in SRT measurements with interrupted noise but not in stationary noise. With non-stationary noise, it is recommended to include a repeated measures design.     

噪声频谱特性对正常听力成人词汇识别影响

目的　探讨噪声频谱特性对词汇识别的影响作用。方法　31名听力正常成人参与研究,研究采用汉语普通话词汇相邻性测试,分别获得言语谱噪声（speech spectrum-shaped noise,SSN）和多人谈话噪声（babble noise,BN）下不同信噪比（signal noise ratio,SNR）的言语识别率,并计算词汇识别率为20%、50%和80%时所需要SNR和斜率,进而分析噪声频谱特性对词汇识别的影响作用。结果　SSN条件下单音节词和双音节词的言语识别阈,即正确识别率为50%所对应的SNR（SNR50）分别为-4.83 dB和-7.63 dB（t 50=11.918,P＜0.05）,对应斜率分别为5.61和11.14（t 50=-7.006,P＜0.05)。BN条件下单音节词和双音节词的SNR50分别为-3.34 dB和-5.52 dB（t 50=8.860,P＜0.05),对应斜率分别为6.04和9.28（t 50=-4.316,P＜0.05）。统计显示SSN和BN下单、双音节词识别阈均有统计学差异（t 50M=-5.037,t 50D=-10.275,P＜0.05）,两类噪声下双音节词的斜率有统计学差异（t 50D=2.920,P＜0.05）。结论　BN噪声频谱掩蔽效应比SSN更强。在两种噪声下,单音节词均需要更高的SNR,才能达到和双音节词相同的词汇识别。     

Adaptation of the HINT (hearing in noise test) for adult Canadian Francophone populations

The HINT provides an efficient and reliable method of assessing speech intelligibility in quiet and in noise by using an adaptive strategy to measure speech reception thresholds for sentences, thus avoiding ceiling and floor effects that plague traditional measures performed at fixed presentation levels. A strong need for such a test within the Canadian Francophone population, led us to develop a French version of the HINT. Here we describe the development of this test. The Canadian French version is composed of 240-recorded sentences, equated for intelligibility, and cast into 12 phonemically balanced 20-sentence lists. Average headphone SRTs, measured with 36 adult Canadian Francophone native speakers with normal hearing, were 16.4?dBA in quiet, ?3.0?dBA SNR in a 65?dBA noise front condition and ?11.4?dBA SNR in a 65?dBA noise side condition. Reliability was established by means of within-subjects standard deviation of repeated SRT measurements over different lists and yielded values of 2.2 and 1.1?dB for the quiet and noise conditions, respectively.     

Introducing real-life listening features into the clinical test environment: Part I: Measuring the hearing performance and evaluating the listening effort of individuals with normal hearing

Objective: Controlled clinical test environments are very different from real-life listening situations in which speaker and background noise level variations can hinder a person’s ability to hear and follow conversations. This study was performed to evaluate the ability of people with normal hearing to follow a single speaker in the presence of background noise, and to explore relations between those measures and the listeners’ subjective assessments, listening effort, and sound quality judgements.

Methods: A group of adults with normal hearing were evaluated using the following battery of tests: (i) Roving Level Test, (ii) the Just Understanding Speech Test, (iii) Performance Perceptual Test, (iv) the Visual Analogue Scale to evaluate listening effort, and (iv) with a sound quality questionnaire.

Results: The results show that people with normal hearing tend to accurately estimate their hearing abilities, and both the listening effort required and speech recognition thresholds tend to increase with increasing background noise.

Discussion: Implementing a battery of tests that evaluate speech-in-noise listening abilities, listening effort, and subjective hearing perception might provide greater insight into hearing performance than traditional measures. Additionally, the data generated in this study can be used for comparison with measures obtained from hearing impaired and hearing device listeners, and as such, has the potential to guide counselling and rehabilitation to a range of clinical populations.

Conclusion: The examination of both the self-estimated and verified performance measurements in simulated real-life listening situations can provide audiologists with a comprehensive and realistic profile of a person’s hearing performance.
