  The number of people using portable audio players has increased significantly over the recent years. This implies the rise in the number of people having hearing loss problems. Therefore, there is a need to find appropriate procedures that simplify the process of the hearing problem detection. Investigations performed show that audiometric tests may not be sufficient to assess hearing in young people. Contrarily, the obtained results...

  The main goal of this research study is focused on creating a method for loudness scaling based on categorical perception. Its main features, such as: way of testing, calibration procedure for securing reliable results, employing natural test stimuli, etc., are described in the paper and assessed against a procedure that uses 1/2-octave bands of noise (LGOB) for the loudness growth estimation. The Mann-Whitney U-test is employed...

  W procesie dopasowania współczesnych aparató słuchowych wymagana jest znajomość charakterystyki dynamiki słyszenia. Charaketrystyka dynamiki słyszenia wyznaczana jest na podstawie wyników testu skalowania głośności. Problem w tym, że wyniki testu skalowania głośności wyrażone są w skali kategorii oceny wrażenia głośności, natomiast aparaty słuchowe wymagają parametrów określonych na skali numerycznej. Logika rozmyta jest jedną...

  A method for fitting the mobile computer audio characteristics to the user's hearing preferences is proposed. The process consists of two stages: calibration and dynamics processing. During the calibration phase the user performs a loudness scaling test giving their response regarding the perceived loudness. The dynamics processing made on above basis sets the loudness to the most comfortable level. The processing accounts both...
