Gardiner brown tuning forks from the UK. Chrome plated steel. Hardened for longer note duration. Thumb grip at base.
Gardiner Brown model. Helpful in determining conductive or sensory neural hearing loss and peripheral neuropathies. Abnormalities are determined based on the number of seconds (plus or minus) from the point when the examiner loses the vibratory sensation vs. when the patient no longer detects the vibratory stimulus. Polished chromed steel.
