| Sumario: | Objective: Conventional hearing tests do not evaluate hearing functions in noisy environments. However, real life also includes noisy environments. In this context, Digit in Noise, a hearing screening test in noisy environments, was developed and countries adapted it to their native language. Aim: The aim of this study is to improve the Turkish Number in Noise Test and evaluate its effectiveness. Desing: The digits were read to a male speaker whose native language is Turkish. Then a mobile application was developed in accordance with the android operating system. The Turkish Number in Noise test mobile application was evaluated in 100 individuals with normal hearing, conductive hearing loss, S/N hearing loss and mixed hearing loss. Results: The mDIN scores of individuals with normal hearing were 39.68±6.82, 36.88±6.31 for conductive hearing loss, 19.40±5.39 for S/N hearing loss and 22.96±4.52 for mixed hearing loss. While there was no significant difference between mGST scores of individuals with conductive hearing loss and normal individuals (p>0.069), there was a significant difference between mGST scores of individuals with S/N type and mixed hearing loss and those with normal hearing (p=0.00). Conclusions: When the Turkish Digit in Noise Test scores were examined, the scores of individuals with S/N type and mixed type hearing loss differed from those of normal hearing.
