“…It therefore makes sense to analyse both parts separately in addition to the whole signal. Due to the psychoacoustic properties of the human hearing organs [18], [19], our subjective perception of gunshots is much longer than the millisecond duration of a purely physical sound signal. It should also be noted that the intensity of the gunshot drops non-linearly with increasing distance from the source (as well as the intensity of other sounds) by absorption in the air and spherical propagation.…”

This paper presents an efficient approach to automatic gunshot detection based on a combination of two feature sets: adapted standard sound features and hand-crafted novel features. The standard features are mel-frequency cepstral coefficients adapted for gunshot recognition in terms of uniform gamma-tone filters linearly spaced over the whole frequency range from 0 kHz to 16 kHz. The first 18 coefficients calculated from the 41 filters represent the best set of the optimized cepstral coefficients. The novel features were derived in the time domain from individual significant points of the raw waveform after amplitude normalization. Experiments were performed using single and ensemble neural networks to verify the effectiveness of the novel features for supplementing the standard features. The novelty of the work is the proposed feature combination, which allows to achieve very effective detection of gunshots from hunting weapons using 23 features and a simple neural network. In binary classification, the developed approach achieved an accuracy of 95.02 % in gunshot detection and 98.16 % in disregarding other sounds (i.e., non-gunshot).

Summary This paper presents an experiment with onomatopoeia formation. Fifty-one Slovak participants were asked to imitate ten sound events of various frequencies by writing down onomatopoeic words using the letters of the Slovak alphabet. The purpose of the experiment was to examine the role of image iconicity in producing new onomatopoeias. Image iconicity is expected to be manifested in the participants’ agreement on the form of the proposed onomatopoeias and, therefore, in the possibility of establishing onomatopoeic patterns. The pattern structure was determined by the realization of five characteristics: initial position, final position, transition, lengthening, and repetition. In addition, the established patterns make it possible to examine the role of sound-symbolism, particularly phonesthemes in the formation of onomatopoeias.
