Correction to: European Archives of Oto-Rhino-Laryngology https://doi.org/10.1007/s00405-021-06811-8

In the original publication of the article, under the section “Material and methods”, the following sentence “This study was conducted in the clinical laboratory of the Audiology Department of Istanbul Aydin University from January–May 2019. It was approved by the Istanbul Aydin University Non-Interventional Clinical Research Ethics Committee (registration number 2019/118) on June 19th, 2019.” was published incorrectly. January–May months should be changed to July–December.

Hence, the correct sentence should read as follows, “This study was conducted in the clinical laboratory of the Audiology Department of Istanbul Aydin University from July–December 2019. It was approved by the Istanbul Aydin University Non-Interventional Clinical Research Ethics Committee (registration number 2019/118) on June 19th, 2019.”

In addition, the figure 1 was published incorrectly and correct Fig. 1 is provided below.
