| abstracts | The results of experiments performed in a wave flume designed to explore
associations between the dissipation of surface wave energy during breaking and acoustic noise
emission are presented. The experiments were carried out using tap water in the wave
laboratory of the Institute of Hydro-Engineering of the Polish Academy of Sciences, Gdańsk,
Poland. In particular, being shown are the parameters of empirical dependency between
the dissipated wave energy during plunging and the energy of pre-breaking wave trains.
Relationships between wave energy losses in the case of breakers with an amplitude of about
10 cm and the noise acoustic energy in the frequency band from 80 to 12,500 Hz were estimated.
Taking into consideration the phenomena of reverberations and propagation in an acoustical
waveguide, a numerical model was used for the correction of the observed noise's acoustic
spectra. A detailed analysis of the factors affecting the noise level in the semi-enclosed volume
allowed us to specify the rate of conversion of the wave energy dissipated during breaking into
acoustic energy, which was found to be in the order of 10-8 |
