Low-pass filtered masking noise makes speech-in-noise tests more sensitive

An easily accessible screening test can be valuable in the prevention of noise-induced hearing loss (NIHL). The Dutch National Hearing Foundation developed ‘Earcheck’, an internet-based speech-in-noise test, presenting CVC-words in stationary broadband noise. However, its sensitivity to detect NIHL appeared to be low, 51% (Leensen et al, 2011, part 1). This study showed that Earcheck with low-pass filtered noise made the best distinction between normal hearing and NIHL, without reducing test reliability. The use of this noise condition improved the sensitivity of Earcheck to 95%. Conclusion: The use of low-pass filtered masking noise makes speech-in-noise tests more sensitive to detect NIHL in an early stage.
