“…We found that some dimensions showed significant differences between left and right ears, such as width of the ear, as shown in Table 4. Jung and Jung (2003) and Fan et al (2019) also reported similar findings in ear height and males' tragal height, respectively. The percentage of measurements with an asymmetry over 2 mm even reached 66.6% (ear connection height of females with |x| > 2 in Table 5).…”

In addition, Ji et al (2017) only measured the dimensions of auricular concha without pinna, which cannot provide the ear pinna details necessary for ear-related product design.…”

Ear anthropometry plays an important role in ear-related product design. However, current Chinese ear anthropometry data do not provide sufficient guidance for product designers targeting young Chinese consumers. In this study, an ear anthropometry survey of 1338 young Chinese college students was conducted using photogrammetry. Eight key dimensions were determined, measured, and statistically analyzed: ear height, ear width, ear length, cavum conchae height, cavum conchae width, ear connection height, ear lobe height, and ear lobe width. Interethnic, intergender, subject-specific, and intrasubject differences were explored and discussed, based on the collected data. In addition, ear shape classification was conducted using principal component analysis to recommend an ear-related product sizing system. The data obtained in this survey can be used as a reference for earrelated product design targeting young Chinese consumers.

“…Human factors, such as anthropometry data, age, and gender, should be considered while designing a workplace's layout or when assigning tasks, as these detail the physical well-being of a worker. Instruments designed without considering anthropometric data are not ergonomically designed and may impose discomfort for workers [45]. Prolonged use of out dated machinery in manufacturing results in vibrations which induce Hand-Arm Vibration Syndrome (HAVS) and hearing problems among workers [46].…”

Role of Ergonomic Factors Affecting Production of Leather Garment-Based SMEs of India: Implications for Social Sustainability

This paper aims to identify, evaluate, and measure the ergonomic factors hampering the production of leather garment-based small and medium-sized enterprises (SMEs). Ergonomic problems faced by the workers largely impact the health of individuals and also the productivity of a firm. Based on experts’ opinions and a literature survey, three emerging categories—namely, occupational disease, personal factors, and the industrial environment—with a total of twenty factors were identified to examine symmetrical impact in five leather garment companies. In this research work, Cronbach’s α was evaluated to check the validity of the ergonomic factors identified through the literature survey. Then, using the fuzzy analytic hierarchy process (FAHP), the identified ergonomic factors were evaluated. A sensitivity analysis was carried out to validate the robustness of the results obtained using the integrated approach. Outdated machinery, vibration, operational setup, fatigue, and poor ventilation and lighting are the top five factors inducing ergonomic-related problems and hampering the production of the leather garment companies in India. These top ergonomic factors are the result of a failure in the provision of an ambient working environment. Providing ergonomically designed working environments may lower the occurrence of ergonomic problems. The findings of this study will assist industrial managers to enhance production rate and to progress towards social sustainability in Indian SMEs. The proposed symmetrical assessment in this study could also be considered as a benchmark for other companies in which human–machine interaction is significant.

“…Especially during these days, with the pandemic caused by Covid-19 and other viruses, where different requirements are published for civilians and for professional caregivers, which sometimes are different for each country. Ergonomic design has become ubiquitous in our society, and this trend is evident in design activities (Fan et al, 2019).…”

The facial fit of respirators is crucial for determining how effectively respirators may protect users from exposure to airborne contaminants, when their use is required in the workplace. In the Chilean market, all the respirators available have been designed and manufactured using foreign regulations. The aim of this research was to determine the facial dimensions in a sample of Chilean workers (users or potential users of respiratory protective equipment) and the possible mismatch between their anthropometric characteristics and the respirator fit test panels proposed by Los Alamos National Laboratory (LANL) and National Institute for Occupational Safety and Health (NIOSH). An anthropometric survey that included 11 measurements was conducted, based on ISO/TS 16976-2 and ISO 15535 to ensure the highest standards possible, and a total of 474 workers (female: 229, male: 245), aged 18-66 years old participated in the survey. The anthropometric measurements were then contrasted with the fit test panels used in LANL (for half and full facepieces) and NIOSH (Bivariate and Principal component analysis (PCA)), to verify the level of mismatch. The results showed that LANL panels presented a level of mismatch of 11.8% and 21% for the half-facepiece and the full-facepiece, respectively. Considering the NIOSH bivariate and PCA panels, 4.6% and 4.4% of the sample remains without an assigned cell, respectively. It can be concluded that the LANL panels for half and full facepieces do not match the facial dimensions of the Chilean working population. The panels developed by NIOSH and considered by the ISO/TS 16976-2 (bivariate and PCA), are applicable to the Chilean working population. Relevance for the Industry: This research provides anthropometric measurements of Chilean workers, to determine the dimensions for half-and full-facepiece respirators, which are currently not available. The NIOSH or ISO fit test panels, as opposed to LANL panels, should be used when manufacturing respirators for Chilean workers.
