Pure tone audiometry indicates what hearing thresholds (dB) are required to just be able to perceive a tone at different frequencies (Hz). A pure tone audiology threshold at a specific frequency is the decibel level at which a sound is perceived 50% of the time. The decibel scale used in pure tone audiometry is dB Hearing Level (dB HL). The dB HL intensity scale is based on normal human hearing...

Speech audiometry is one of the methods for evaluating hearing status, and recently it’s tended to be implemented on mobile phones with the development of internet and smart devices. Although several applications include the function of speech audiometry, the effectiveness of this function was rarely reported. In this work, we developed an Apple iOS-based application (Hearing Assistant) with fu...

BACKGROUND Potential methods of application of self-administered Web-based pure-tone audiometry conducted at home on a PC with a sound card and ordinary headphones depend on the value of measurement error in such tests. OBJECTIVE The aim of this research was to determine the measurement error of the hearing threshold determined in the way described above and to identify and analyze factors in...

As audiology strives for cost containment, standardization, accuracy of tests, and accountability, greater use of automated tests is likely. Highly skilled audiologists employ quality control factors that contribute to test accuracy, but they are not formally included in test protocols, resulting in a wide range of accuracy, owing to the various skill and experience levels of clinicians. A meth...

UNLABELLED The authors evaluated pure tone audiometry with and without specific ear protectors. AIM The purpose of this case control study was to measure the level of sound attenuation by earplugs. MATERIAL AND METHODS The evaluation included sixty ears of 30 subjects of both sexes, aged between 20 and 58 years, of various professional activities, with normal hearing thresholds, and followi...

OBJECTIVE The timely diagnosis of hearing loss in the pediatric population has significant implications for a child's development. However, audiological evaluation in this population poses unique challenges due to difficulties with patient cooperation. Though specialized adaptations exist (such as conditioned play audiometry), these methods can be time consuming and costly. The objective of thi...

Chronic tinnitus can often be temporally associated with a loss of sensorineural hearing. However, also occur in people normal hearing and thus arise without traceable disorder the inner ear. In present study, we tested whether fine-structure audiometry or high-resolution measurement otoacoustic emissions reveal evidence inner-ear-related disorders that remain undetected by conventional manual ...

introduction: the incidence of multidrug resistant tuberculosis is increasing in developing countries. aminoglycosides are an integral part of second-line drugs, however ototoxicity is a major limitation for their use. this study aims to determine the extent of hearing loss in patients taking one of the commonly prescribed drugs for multidrug resistant tuberculosis (mdr-tb), kanamycin, at a gov...

UNLABELLED In otosclerosis patients the most common procedure followed at Otosurgical Dept. Medical University of Lodz is stapedotomy with insertion of teflon-piston prosthesis. When surgery is finished a whisper hearing test is done from the 1 meter distance for brief intraoperative hearing improvement assessment. There is a number of patient who report subjective intraoperative hearing improv...
