“…Hearing assessment followed a two-stage process: hearing screening and PTA. The hearing was screened with the Dutch/Flemish version of the digit triplet test, which is a paradigm with high sensitivity and specificity for detecting sensorineural HL [41]. Three speech digits are presented in noise, and the signal-to-noise ratio (SNR) was varied adaptively until a speech reception threshold (SRT) was achieved.…”

“…Per ear, it takes about 3 min to determine the SRT in steady-state noise. The DTT is less time-consuming than pure-tone audiometry and does not require a sound booth nor an experienced audiologist [41,42].…”

“…It has been translated and validated for many languages following the first Dutch version [59]. High sensitivity and specificity values of >80% are obtained; for a recent review, see Van den Borre et al, 2021 [41]. DTTs require only a minimum of linguistic and cognitive abilities, have a high measurement precision (test-retest reliability <1 dB), and can generally be conducted in less than five minutes [42].…”

Long-term exposure to occupational noise is often associated with noise-induced hearing loss (NIHL) among dentists. This study aims to investigate potential hearing loss (HL) and self-reported annoyance as a result of exposure to noise produced by contemporary dental equipment. Methods: Three cohorts participated: 53 dentists with more than 5 years of service, 47 dentists with at most 5 years of service, and 53 pharmacists as controls, age and gender-matched to the first group. After the exclusion of one person, the hearing of 304 ears was screened with the Flemish version of the digit triplet in noise test (DTT). If screening failed, otoscopy and pure tone audiometry (PTA) were performed for both ears. Furthermore, general information, knowledge, exposure, annoyance, general health, and preventive measures were assessed with a custom-made questionnaire. Results: NIHL did not occur significantly more often with dentists than with controls. However, dentists revealed a significantly higher annoyance (related to the noise from their equipment) and reported more complaints than the pharmacists. All three groups indicated lack of knowledge on hearing care. Conclusions: While noise levels in contemporary dentistry are not harmful and do not induce NIHL, the sounds emitted by the devices are disturbing and affect mental health. This study calls for increased awareness of the consequences of sound exposure and stresses the need to monitor and protect the hearing of dentists regularly.

“…Mobile applications that do not use tonal stimuli usually employ a speech-in-noise procedure to measure hearing at conversational loudness levels [24]. One measure commonly used is the digits-in-noise (DIN) test, which presents a series of three spoken digits (e.g., 3-5-8) in background masking noise [31]. The DIN varies the noise level relative to that of the digits up and down to find the ratio, termed the speech recognition threshold (SRT), where 50% of the digits are accurately recognized.…”

“…The DIN varies the noise level relative to that of the digits up and down to find the ratio, termed the speech recognition threshold (SRT), where 50% of the digits are accurately recognized. The DIN SRT measure has strong reliability and validity and high sensitivity and specificity to detect hearing loss measured with pure-tone audiometry [31][32][33][34][35]. Moreover, unlike audiometry, the DIN is accurate across different devices and headphone types without the requirement of calibration (Table 1) [35].…”

Digital Technology for Remote Hearing Assessment—Current Status and Future Directions for Consumers

Globally, more than 1.5 billion people have hearing loss. Unfortunately, most people with hearing loss reside in low- and middle-income countries (LMICs) where traditional face-to-face services rendered by trained health professionals are few and unequally dispersed. The COVID-19 pandemic has further hampered the effectiveness of traditional service delivery models to provide hearing care. Digital health technologies are strong enablers of hearing care and can support health delivery models that are more sustainable. The convergence of advancing technology and mobile connectivity is enabling new ways of providing decentralized hearing services. Recently, an abundance of digital applications that offer hearing tests directly to the public has become available. A growing body of evidence has shown the ability of several approaches to provide accurate, accessible, and remote hearing assessment to consumers. Further effort is needed to promote greater accuracy across a variety of test platforms, improve sensitivity to ear disease, and scale up hearing rehabilitation, especially in LMICs.
