“…Speech, being an acoustic signal rich in information, inherently captures attention in the mind, often involuntarily. As a consequence, the audibility and intelligibility of speech in the environment can draw attention and, in the worst-case scenario, disrupt concentration at work [14,15]. Speech can range from imperceptible and barely noticeable to intelligible or completely understandable, with various intermediate levels defined on a scale of perception.…”

This paper examines speech privacy in both residential and commercial spaces. The ASTM E2638 standard defines the Speech Privacy Class (SPC) parameter, which measures speech privacy based on the signal-to-noise ratio at the listener’s position. This paper proposes estimating the SPC value using relevant ISO parameters commonly used in European practice: the apparent sound reduction index in dB (defined by ISO 16283-1, 2 standards) and the equivalent ambient noise level in dBA (defined by the ISO 1996-1 standard). The estimated value of the SPC parameter in this paper is referred to as the Speech Privacy Index (SPI). A diverse range of situations, i.e., rooms, was analyzed in the field. These rooms varied in terms of purpose, organization, dimensions, furnishings, isolation from other spaces, and internal and external environments. The results of the experiments demonstrate a strong correlation between the SPC value estimated according to ISO parameters (the proposed method) and the SPC as defined in the ASTM E standard. This indicates that the proposed method can provide an indicator of the state of speech privacy in buildings. The significance of the proposed calculation method (i.e., the STI parameter) lies in its ability to be applied at the building design stage, as well as after its completion, during routine testing.

“…Research related to speech privacy in the literature primarily refers to office buildings, meeting rooms and open-plan offices [28,29]. Some research specifically looks at user satisfaction with speech privacy [14]. Research on speech privacy measurements in buildings can be found [30], as well as studies on speech privacy prediction [31].…”

“…In addition to lighting and noise levels, temperature and thermal comfort are also found relevant to job satisfaction and efficiency. In a study conducted by Lee et al [18], which aimed to identify the effects and relationship of indoor workplace design to personal factors in South Korea, it was revealed that thermal comfort is a major source of environmental quality and job satisfaction. Lastly, the design of the workstation is also found to be significant to job satisfaction.…”

The business process outsourcing (BPO) sector is important in managing business especially in a developing country like the Philippines. Call centers are one of the most common type of industries within the BPO sector as they generate 75.1% of its revenues. Given the lack of studies regarding the ergonomic factors in the BPO industry, the goal of this research is to examine the relationships of different ergonomic domains on the job satisfaction and overall productivity of the BPO agents in a customer service or call center industry. The data were gathered through an online survey and the approach used for this study was a variance-based partial least squares structural equation modeling (PLS-SEM) with maximum likelihood estimation. Through analysis, it was proven that macro-ergonomics and physical ergonomics have significant effects on the overall productivity of BPO workers, while cognitive and macro-ergonomics have a significant influence on job satisfaction. In addition to this, it was also proven in the study that overall productivity and job satisfaction were significantly associated. This is one of the first studies to investigate and examine the relationship between ergonomic domains and the productivity and job satisfaction of a Filipino BPO or call center worker. The results of this study could be used as a reference for further investigations by future researchers, especially on more ergonomic factors as well as the extrinsic variables that were not covered by the researchers of this paper. In addition to this, the proposed framework might also be adapted and used as a reference for further studies to produce more accurate and updated results.
