In the internal combustion engine noise source separation process, the combustion noise and the piston slap noise are found to be seriously aliased in time-frequency domain. It is difficult to accurately separate them. Therefore, the noise source separation method which is based on Gammatone filter bank and robust independent component analysis (RobustICA) is proposed. The 6-cylinder internal combustion engine vibration and noise test are carried out in a semianechoic chamber. The lead covering method is adopted to isolate the interference noise from numbers 1 to 5 cylinder parts, with only the number 6 cylinder parts left bare. Firstly, many mode components of the measured near-field radiated noise signals are extracted through the designed Gammatone filter bank. Then, the RobustICA algorithm is utilised to extract the independent components. Finally, the spectrum analysis, the continuous wavelet time-frequency analysis, the correlation function method, and the drag test are employed to further identify the separation results. The research results show that the frequency of the combustion noise and the piston slap noise are, respectively, concentrated at 4025 Hz and 1725 Hz. Compared with the EWT-RobustICA method, the separation results obtained by the Gammatone-RobustICA method have very fewer interference components.

“…The human sound perception of sound quality is not only represented by sound pressure level (SPL) (LIU; DONG; ZHAO, 2017;ZWICKER;FASTL, 2013), but also by the customer psychological feelings of the noise (SUN et al, 2017). Therefore, to improve the sound quality, studies have been conducted on the use of objective psychoacoustics metrics such as A-weighted sound pressure level, loudness, sharpness, and fluctuation strength (ZHAO; WU, 2020), jury tests (TUZE; K; M, 2020) that directly access the subjective perception of humans and correlations of both (BAARS; LENZI; NUNES, 2002) as the former provides a straightforward objective tool, while the latter requires time, statistical data processing, and ethical aspects due to the involvement of humans for the data acquisition.…”

The aims of this study are to identify via harnessing noise mapping the effects of noise pollution at Çukurova University campus on the academic setting and to reveal the obtained change values in noise pollution on the campus during the period 2010-2017. In line with these aims, the first step has been to map the highway-induced environmental noise on Çukurova University campus during daytime (07:00-19:00) and evening (19:00-23:00) hours by employing SoundPLAN 7.3 software. Traffic-induced noise distribution maps for years 2010 and 2017 on the campus were analyzed by threshold values stipulated by the Regulation on Environmental Noise Assessment and Management that is compliance with the European Union Directive on Environmental Noise (2002/49/EC) and after the conducted analyses, traffic-induced environmental noise measured on Çukurova University campus since the past to that date was identified in terms of spatial change. The Regulation defines threshold values, namely, (1) 65 dB(A) for daytime from 07:01 to 19:00, (2) 60 dB(A) for evening-from 19:01 to 23:00, (3) 55 dB(A) for night time-from 23:01 to 07:00. It was then identified in the research area that faculty buildings of Science and Letters, Engineering, Architecture, Faculty of Economics and Administrative Sciences, Dentistry, Faculty of Law, and Communication devoid of any vegetation space to set a barrier between emission-source highway and front walls of buildings facing the roadside were the structures most severely exposed to the noise. In the research area, the comparison of year 2017 noise distribution with respect to year 2010 manifested that the regions exposed to noise value 35 dB(A) and below, 35-45 dB(A), and 45-55 dB(A) levels decreased while a proportional increase was detected in regions exposed to 60 dB(A) noise value that is close to the legal threshold value and noise level above 65 dB(A).
