Tolerable delay for speech production and perception: effects of hearing ability and experience with hearing aids.

Int J Audiol. 2017 Aug 24;:1-8

Authors: Goehring T, Chapman JL, Bleeck S, Monaghan JJM

Abstract
OBJECTIVE: Processing delay is one of the important factors that limit the development of novel algorithms for hearing devices. In this study, both normal-hearing listeners and listeners with hearing loss were tested for their tolerance of processing delay up to 50 ms using a real-time setup for own-voice and external-voice conditions based on linear processing to avoid confounding effects of time-dependent gain.
DESIGN: Participants rated their perceived subjective annoyance for each condition on a 7-point Likert scale.
STUDY SAMPLE: Twenty normal-hearing participants and twenty participants with a range of mild to moderate hearing losses.
RESULTS: Delay tolerance was significantly greater for the participants with hearing loss in two out of three voice conditions. The average slopes of annoyance ratings were negatively correlated with the degree of hearing loss across participants. A small trend of higher tolerance of delay by experienced users of hearing aids in comparison to new users was not significant.
CONCLUSION: The increased tolerance of processing delay for speech production and perception with hearing loss and reduced sensitivity to changes in delay with stronger hearing loss may be beneficial for novel algorithms for hearing devices but the setup used in this study differed from commercial hearing aids.

More Infants are Benefiting from Newborn Hearing Screenings

A CDC Morbidity and Mortality Weekly Report found more infants are receiving documented newborn hearing screening and early intervention services. (2017;66[33]:888.) National early hearing detection and intervention (EHDI) data showed that the percentage of newborns who had documented newborn hearing screening increased from 52 percent to over 97 percent between 2000 and 2014. From 2005 to 2014, documented enrollment in early intervention from 2005 to 2014 among newborns who received documented screening increased from 58 percent to 65 percent. The number of infants lost to follow-up reduced both overall and in selected states. For example, only 4.6 percent of infants who did not pass newborn hearing screening in Massachusetts in 2014 were lost to follow-up, and 85 percent of newborns with diagnosed hearing loss were documented to have received intervention services.

​Early diagnosis of hearing loss, starting with newborn screening, has been shown to reduce deficits in receptive and expressive language that occur in unscreened children who subsequently receive a clinical diagnosis of hearing loss. (Pediatrics. 2016;137[1].) The authors of the report hope the lessons learned from the success of newborn hearing screening programs could be applied to early detection and intervention initiatives for critical congenital heart disease and other health conditions.​
