abstract = {The recording of Transient Evoked Otoacoustic Emissions (TEOAEs) has become one of the most important clinical tests of the functionality of the inner ear, but up to now, TEOAEs analysis still relies mostly on a visual inspection of the signal in the time domain. Because of the non-stationary and non-linear nature of the TEOAEs, proper description of the TEOAEs requires simultaneous localization of signal’s structures in time and frequency domains. Existing methods of time-frequency representation of TEOAEs suffer from drawbacks such as limited time or frequency resolution and artefacts that make them impractical for practical use. 

It will be presented a new method for TEOAEs analysis using recently proposed Hilbert-Huang transform (HHT). The method consists of the empirical mode decomposition (EMD), which is then decomposed into a set of intrinsic mode functions (IMFs). The Hilbert transforms can then be applied to the IMFs. The local energies and the instantaneous frequencies derived from the IMFs through Hilbert transforms can be used to construct a full energy-frequency-time distribution of the data. 

The results obtained using the proposed method are compared to other time-frequency representations (short time Fourier transform, smoothed Wigner-Ville distribution and wavelet transform). The results show that the HHT method is superior to other time-frequency representations and gives the most precise definition of particular events in time-frequency space. The HHT is expected to be useful tool for analysing TEOAEs in a clinical practice.},

abstract = {The aim of this study is to evaluate the Time-Frequency properties of Transiently Evoked Otoacoustic Emissions (TEOAEs). 

Hilbert Spectrum Analysis method was applied to obtain Time-Frequency representations from neonatal and children TEOAEs. It is argued that Hilbert Spectrum Analysis in comparison with other Time-Frequency methods is more appropriate, because of transient and non-stationary nature of TEOAEs. 

Results indicate that Hilbert Spectrum Analysis gives the superior resolution and most detailed information from TEOAEs.},

Distortion product Otoacoustic Emissions (DPOAEs) was used because of their relation with function of peripheral auditory system. The results achieved demonstrate that electromagnetic fields from GSM cellular phones affect amplitude of DPOAEs. 

The possible Electromagnetic Interference (EMI) effects on the measurement equipment are discussed.},

abstract = {Otoacoustic emission (OAE) is a weak sound caused by motion of the eardrum in response to vibrations from the deep within the cochlea. OAE is a quick and non–invasive technology to evaluate inner hair cell function. The purpose of the work was to test hearing capabilities of young musicians. This was achieved by measurements of OAE tone and impedance audiometry. It was explored that OAE signals by musicians are similar to individuals working in high noise conditions. Therefore children have a greater risk of noise–induced hearing loss.},
