Medical diagnostic tuning fork designed primarily for Rinne and Weber hearing tests, air-conduction and bone-conduction comparison, and bedside hearing assessment, with durable steel construction and an extended smooth-metal handle for convenient clinical use.
The IndoSurgicals Tuning Fork 512 Hz is a medical diagnostic instrument designed for bedside assessment of hearing and is particularly suitable for performing Rinne and Weber tuning-fork tests.
The 512 Hz frequency is widely used in clinical hearing examination because it provides a useful balance between audible tone duration and relatively low tactile vibration. This helps reduce the possibility of a patient confusing physical vibration with an audible sound during bone-conduction testing.
Its durable steel construction, lightweight design and extended turned smooth-metal handle make the instrument convenient for doctors, ENT professionals, healthcare practitioners, hospitals, clinics and medical teaching institutions.
A commonly preferred tuning-fork frequency for bedside hearing assessment because it provides a clinically useful audible tone while producing less tactile vibration than lower-frequency tuning forks.
A commonly preferred frequency for clinical Rinne and Weber tuning-fork hearing tests.
Suitable for comparing air conduction and bone conduction during bedside assessment of hearing.
Suitable for assessing lateralisation of sound during clinical evaluation of asymmetric hearing impairment.
Extended smooth handle allows convenient placement against appropriate bony landmarks during examination.
Manufactured from quality steel for durability and dependable mechanical performance in professional use.
Covered by a one-year warranty against applicable manufacturing and material defects.
The Rinne test compares a patient's perception of sound through air conduction and bone conduction. It provides useful bedside information when assessing possible conductive hearing loss.
The Weber test evaluates whether a bone-conducted tone is perceived equally in both ears or lateralises toward one side, assisting clinical assessment of asymmetric hearing loss.
Rinne and Weber findings can be combined with history, otoscopy and formal audiological testing when evaluating a patient with suspected hearing impairment.
Selecting an appropriate tuning-fork frequency is important during hearing assessment. Lower-frequency tuning forks produce stronger tactile vibration, while very high-frequency forks have a shorter audible decay time.
Compared with 128 Hz and 256 Hz forks, a 512 Hz tuning fork produces less prominent tactile vibration, helping the patient distinguish sound from vibration.
The frequency provides sufficient audible duration for practical comparison of air and bone conduction during a Rinne examination.
The 512 Hz tuning fork is widely used for routine bedside Rinne and Weber testing in ENT and general medical examination.
The Rinne test compares air conduction with bone conduction in each ear. It is a bedside screening examination that can help identify a pattern consistent with conductive hearing impairment.
Hold the tuning fork by its handle and activate the tines using an appropriate clinical technique to produce a clear audible tone.
Place the base of the vibrating tuning fork on the mastoid area according to the standard examination technique and ask the patient to indicate when the tone is no longer heard.
Move the vibrating tines appropriately near the external auditory canal and ask whether the patient can again hear the tone.
In normal hearing and many sensorineural losses, air conduction is typically perceived better than bone conduction. A reversal of this relationship may indicate a conductive component and requires appropriate clinical interpretation.
The Weber test assesses lateralisation of a bone-conducted sound and is commonly performed together with the Rinne test.
The base of the activated tuning fork is placed on an appropriate midline bony location, commonly the forehead or another suitable midline site according to the examiner's technique.
The patient is asked whether the tone is heard equally in both ears or louder in one ear. Lateralisation is interpreted together with the Rinne test and other hearing findings.
Conductive hearing impairment alters transmission of sound through the external or middle ear. Rinne and Weber responses may show characteristic patterns that help the clinician decide whether further audiological evaluation is required.
Sensorineural hearing impairment involves the inner ear or auditory neural pathway. Weber lateralisation and Rinne findings are interpreted together when assessing possible asymmetric sensorineural loss.
The IndoSurgicals Tuning Fork 512 Hz is constructed from quality steel and designed for repeated professional examination.
Its extra-long, turned smooth-metal handle provides a comfortable holding area and facilitates controlled placement during bone-conduction examination while helping minimise unnecessary contact with the vibrating tines.
The compact design makes the tuning fork convenient for outpatient clinics, bedside examination, examination kits and medical teaching.
The instrument operates entirely through mechanical vibration and requires no battery, charger or external electrical power source.
Different frequencies provide different combinations of audible tone, tone duration and tactile vibration. The appropriate frequency should therefore be selected according to the clinical examination being performed.
The Tuning Fork 512 Hz is a simple but valuable bedside examination instrument for ENT specialists, physicians, general practitioners, audiology professionals and other trained healthcare personnel.
It is also suitable for medical colleges and clinical-skills laboratories where students learn standard Rinne, Weber and bone-conduction examination techniques.
