Directional Processing and Noise Reduction in Hearing Aids: Individual and Situational Influences on Preferred Setting

Abstract: Although the current study lends some support to the view that PTA and cognitive factors affect preferred DIR and NR setting, it also indicates that these effects can vary across noise management technologies. To facilitate more personalized HA fittings, future research should investigate the source of this variability.

“…In other words, NR processing involves a trade-off between desirable noise attenuation and undesirable speech distortions (e.g., Kates, 2008), and there are indications that HA users respond differently to these conflicting effects (Houben et al, 2012a;Marzinzik, 2000). In a number of recent studies, we have investigated the influence of individual factors on experienced HA users' preference for, and speech recognition with, different NR settings (Neher, 2014;Neher, Grimm, Hohmann, & Kollmeier, 2014;Neher, Wagener, & Fischer, 2016). Our data analyses revealed considerable inter-individual variability in preferred NR setting.…”

“…The participants were recruited from a cohort of 60 habitual HA users who had all taken part in our two previous studies (Neher, 2014;Neher et al, 2016). These studies had taken place about 1 year prior to the measurements reported here.…”

“…Hearing-aid fitting mainly 49 consists of the adjustment of amplification parameters to compensate for audibility loss 50 and impaired loudness perception. Advanced hearing-aid signal processing features such 51 as beamforming and noise reduction are typically not individually adjusted in this process, 52 even though they could, in principle, be targeted towards the compensation of supra-53 threshold hearing deficits (Kiessling, 2001;Neher et al, 2016). However, the 54 characterization of individual supra-threshold hearing deficits can be complex and requires 55 loss of outer hair cells (OHC; Ahroon et al, 1993) and/or inner hair cells (IHC; Lobarinas,79 Salvi, & Ding, 2013), and was characterized by sloping audiograms.…”

“…In addition to the input-dependent gain-frequency response prescribed by the fitting rationale, most modern hearing aids include various types of adaptive signal processing to address specific needs in certain sound environments. Features such as noise reduction and adaptive directional microphones will change the gain depending on the characteristics of the sound environment in order to meet the assumed needs of the user in specific environments (e.g., Bentler, 2005; Chung, 2004; Desjardins, 2016; Neher, Wagener, & Fischer, 2016). Furthermore, sound-classification systems have been developed to classify different sound environments into a number of predefined categories that are associated with different settings of the hearing-aid parameters (e.g., Alexandre, Cuadra, Rosa, & Lopez-Ferreras, 2007; Büchler, Allegro, Launer, & Dillier, 2005; Nordqvist & Leijon, 2004).…”
