“…This test was developed by Amiri et al, to evaluate the speech perception in the presence of different background noises in elderly normal pure tone audiogram listeners. In the IMM test, the amount of IM was measured under a total of 20 conditions: five SNRs, two spatial conditions and two genders of background noise [25].…”

“…The IMM test [25] was repeated one session after the completion of training and one month later, and the results were compared with those before the training. This test was conducted at five SNRs as follows: ±5, 0, and ±10, with the target and competing signals being colocated and at 90-degree separation.…”

Background and Aim: Generally, in noisy environments more informational masking occurs. Older adults benefit less than younger adults from spatial hearing and they have more problems of understanding speech in the presence of distracting speeches. This study was conducted to examine the effect of auditory spatial training on informational masking release in the elderly. Methods: Thirty-two 60-75-year-olds with normal hearing, who complain about difficulty in speech perception in noise, participated in control and intervention groups (16 people in each group). The intervention included fifteen sessions of auditory spatial training. The informational masking measurement test scores were compared before the intervention, one session after the intervention, and one month after between the two groups. Results: There was a significant improvement in informational masking measurement scores in the intervention group compared to the control (p<0.02). The results showed no significant differences between the informational masking measurement scores before and after the intervention in the control group (p>0.05) and a significant difference in most signal to noise ratio i.e. 0, -5 and -10, in the intervention group (p≤0.006). No significant difference was found between the results of the two assessments one session and one month after the intervention in any of the positions (p>0.05), which suggests that both groups’ scores remained highly stable one month after the intervention Conclusion: This study introduced a spatial training program to improve speech perception in noise in normal-hearing elderly listeners. It was recommended that this kind of training be included in geriatric population auditory rehabilitation programs.

“…In a recent study conducted by Amiri et al on two groups of young and elderly normal hearing listeners, found that the speech perception ability of elderly listeners is considerably reduced in the presence of meaningful background noise. Moreover, the decrease in SNR significantly reduces the perceptual abilities of elderly listeners [39].…”

Background and Aim: In noisy environments, two types of masking including energetic masking (EM) and informational masking (IM) occur. EM results from the spectral overlap of the target and maskers on the basilar membrane, while IM occurs at higher level. This paper aimed to review the concept of IM in terms of historical perspective and definitions, the important cues for releasing from it, age-related effects and its neural basis. Recent Findings: The data from psychoacoustic, behavioral, and neuro-imaging studies were reviewed and discussed in order to provide an overall image of IM. According to these studies, it seems that perceptual segregation between the target and maskers is the most important cues for releasing from IM. This process takes place simply and without any effort in adults with normal hearing; however, it does not occur easily in children, elderly people and those with impaired hearing. Moreover, it seems that both top-down and bottom-up processing are involved in IM formation. Conclusion: Since IM leads to failure in selection of auditory objects and prevents the individual from auditory scene analysis, understanding the IM concept leads to a better knowledge of speech perception in noise.

“…In some cases, additional tests are developed for use in specific populations, as in the case of AzBio [ 43 ], which is used with people with cochlear implants. Other tests have emerged as a consequence of technological advances, greater accessibility by individuals, or lower cost, such as those that allow the initial screening of hearing using mobile phones [ 44 , 45 , 46 , 47 ].…”

Design and Development of a Spanish Hearing Test for Speech in Noise (PAHRE)

Background: There are few hearing tests in Spanish that assess speech discrimination in noise in the adult population that take into account the Lombard effect. This study presents the design and development of a Spanish hearing test for speech in noise (Prueba Auditiva de Habla en Ruido en Español (PAHRE) in Spanish). The pattern of the Quick Speech in Noise test was followed when drafting sentences with five key words each grouped in lists of six sentences. It was necessary to take into account the differences between English and Spanish. Methods: A total of 61 people (24 men and 37 women) with an average age of 46.9 (range 18–84 years) participated in the study. The work was carried out in two phases. In the first phase, a list of Spanish sentences was drafted and subjected to a familiarity test based on the semantic and syntactic characteristics of the sentences; as a result, a list of sentences was selected for the final test. In the second phase, the selected sentences were recorded with and without the Lombard effect, the equivalence between both lists was analysed, and the test was applied to a first reference population. Results: The results obtained allow us to affirm that it is representative of the Spanish spoken in its variety in peninsular Spain. Conclusions: In addition, these results point to the usefulness of the PAHRE test in assessing speech in noise by maintaining a fixed speech intensity while varying the intensity of the multi-speaker background noise. The incorporation of the Lombard effect in the test shows discrimination differences with the same signal-to-noise ratio compared to the test without the Lombard effect.
