In patients with unilateral sensorineural hearing loss, the phase differences and intercochlear intensity lead to vibrations being sensed louder in the contralateral normal ear, causing sound lateralization.Ĭopyright © 2023, StatPearls Publishing LLC. Objectives: Weber test is typically conducted using tuning forks, but an audiometer can also be used for a similar purpose. Clinical and animal studies have shown that cochlea is stimulated by bone conduction mainly through two routes: 10.2310/7070.2007.0025 Abstract Objective: The purpose of this study was to determine the accuracy of the Rinne and Weber tuning fork tests in predicting the degree of hearing loss secondary to otitis media with effusion (OME) in children compared with pure-tone audiometry. The mechanism underlying sound lateralization of the Weber test has been intriguing to health professionals for many decades. In conductive hearing loss, the sound should lateralize to the affected side however, in patients with sensorineural hearing loss, the sound lateralizes to the contralateral side. The patient who has over eight years old can go for conductive loss test or asymmetric hearing in the low frequencies. It is used to differentiate between sensorineural or conductive hearing loss. The Weber test is often combined with the Rinne test to detect the location and nature of the hearing loss. Objective(1) Determine whether tuning fork material (aluminum vs stainless steel) affects Rinne testing in the clinical assessment of conductive hearing loss (CHL). Overview of Tuning Fork Test is useful in assessing hearing loss. The inner ear mediates sensorineural hearing. The outer and middle ear mediate conductive hearing. The test can detect unilateral conductive and sensorineural hearing loss. Unilateral conductive hearing loss: lateralize to affected ear. Normal: heard equally loud in both ears (also equal in symmetric bilateral hearing loss). The Weber test is a useful, quick, and simple screening test for evaluating hearing loss. Conductive loss can be assessed with the Rinne and Weber test Weber: Place the tuning fork in the midline and determine which ear its heard louder. The Weber test has been mainly used to establish a diagnosis in patients with unilateral hearing loss to distinguish between conductive and sensorineural hearing loss.
Conclusion: SPWT can serve as an auxiliary diagnostic tool in the absence of a 512-Hz tuning fork to assist in the identification of the type of HL and to potentially hasten the diagnosis and provision of treatment when indicated.Tuning fork tests have been the mainstay of otologic examination for more than a century. The sensitivity and specificity of the SPWT were 76.9 and 97.1%, respectively.
Nevertheless, AW and TFW tests' performance compared to pure-tone audiometry (PTA) has yet to be studied. In a normal test, there is no lateralization of sound. Compared to the tuning fork Weber (TFW) test, performing the audiometric Weber (AW) test offers many advantages. Weber test: Place the base of a struck tuning fork on the bridge of the forehead, nose, or teeth. The sensitivity and specificity of the TFWT were 84.6 and 94.1%, respectively. Objectives: Weber test is typically conducted using tuning forks, but an audiometer can also be used for a similar purpose. The SPWT was in agreement with the TFWT (at a frequency of 512 Hz) in 55 (92%) patients. Results: Twenty-six (43%) patients were diagnosed with a SNHL, and 34 (57%) with a CHL. They were asked to press a single uncovered smartphone on their forehead and conduct a Weber test by means of the smartphone’s vibration application. Methods: Sixty patients referred to the emergency department due to unilateral hearing loss (HL) were enrolled. Study Design: We conducted a prospective, noncontrolled clinical study. Objective: The aim of this paper was to compare the accuracy of a smartphone-based Weber test (SPWT) with the traditional tuning fork Weber test (TFWT) in identifying and differentiating between sensorineural hearing loss (SNHL) and conductive hearing loss (CHL).
