Abstract
The application relates to a method for recording auditory steady-state responses responses of a person, the method comprising a) providing an acoustic stimulus signal to an ear of the person, b) recording the auditory steady-state responses of the person originating from said acoustic stimulus signal. The application further relates to a system. The object of the present application is to excite the auditory system with a signal capable of assessing the auditory systems ability to process speech. The problem is solved in that the acoustic stimulus signal comprises a speech-like stimulus provided as a combination of a series of frequency-specific stimuli, each having a specified (e.g. predetermined) frequency bandwidth, presentation rate, amplitude and amplitude-modulation. An advantage of the disclosure is that it allows a clinical assessment of the effect of a hearing device in a normal mode of operation, i.e. when processing speech stimuli. The invention may e.g. be used for diagnostic instruments for verifying the fitting of a hearing aid.
