Abstract Active vibration control (AVC) based on adaptive finite impulse response (FIR) filters inhere delays in conditional signal dispersion. Reasons for these delays are geometrical arrangements, and computational time in analog digital converters (ADCs) and in digital analog converters...
Abstract From 203 cases of low-frequency complaints a random selection of twenty-one cases were investigated. The main aim was to answer the question whether the annoyance is caused by an external physical sound or by a perceived but physically non-existing sound, i.e. low-frequency tinnitus....
Abstract Background: Potential bio-behavioral effects of infrasonic energy (<20 Hz) have generally been considered to be due to extra-aural (non-hearing) mechanisms. Since systems that deliver acoustic energy, including infrasound, are being considered for use as non-lethal weapons, it is...
Abstract This paper presents the development of minimum effort active noise control theory for feedforward single-input single output (SISO) architecture, which includes the feedback acoustic path in the controller formulation. The theoretical range of effective minimum effort parameter with...
A small group (n=9), whose complaints of low frequency noise had not been resolved by Environmental Health Officers and related care professionals, were invited to attend a series of intervention sessions led by a psychotherapist. The aims of the sessions were to improve the participants' coping...
