Audiometric notch as a sign of noise induced hearing loss D I McBride, S Williams Abstract Objectives—To investigate the relation between diVerent types of exposure to noise and a classic sign of noise induced hearing loss (NIHL), the audiometric notch. Methods—The study sample had exposure to both continuous and impulse noise and

Although the characteristic pattern of NIHL was recognised early in the development of pure tone audiometry, the progression of this loss was first studied systematically in cross sectional studies of the Jute industry in Dundee1 and in a cross section of general workplaces in England and Wales.2 These confirmed that with exposure to broad band, steady …

Objective: Bilateral audiometric notch (BN) at 4000-6000 Hz was identified as a noise-induced hearing loss (NIHL) phenotype for genetic association analysis in college-aged musicians. This study analysed BN in a sample of US youth. Design: Prevalence of the BN within the study sample was determined and logistic-regression analyses were performed to identify audiologic and …
Audiogram notches in noise-exposed workers

Abstract. Objectives: Diagnostic criteria for noise-induced hearing loss include the audiometric notch, yet no standardized definition exists. This study tested whether objective notch metrics could match the clinical judgments of an expert panel.

Audiometric notch as a sign of noise induced hearing loss 47 large switches in use in electricity transmission circuits which use a blast of high pressure air to extinguish the arc which forms when the circuit is broken. The peak sound level produced by this apparatus is of a magnitude in the order of that due to firearms and the peak impulse

Background: The definition of notched audiogram for noise-induced hearing loss (NIHL) is presently based on clinical experience, but audiometric phenotypes of NIHL are highly heterogeneous. The data-driven clustering of subtypes could provide refined characteristics of NIHL, and help identify individuals with typical NIHL at diagnosis.

The results of a hearing test, or audiometric test, are recorded on an audiogram. An audiogram is used to chart the results according to loudness (dB) and pitch (Hz).On an audiogram, noise induced hearing loss (NIHL) will usually be seen first as a slight loss of hearing in the 4 kHz region. This dip in hearing is more commonly known as a ‘notch’ in the audiogram.

With respect to the anticipated pattern of hearing loss identified audiometrically, the identification of a notch, dip or bulge, centered at the 4-kHz frequency is considered to be pathognomonic ( Colvin & Luxon 2007; Luxon & Prasher 2007 ).
