“…Hodgson et al 23 found that an appropriate sound environment in restaurant spaces requires background noise level and reverberation time that are neither too low nor too high. However, the appropriate reverberation time and background noise level for nursing homes have not yet been clarified.…”

Sound environment quality in nursing units in Chinese nursing homes: A pilot study

2020

Recent studies have investigated sound environment in nursing homes. However, there has been little research on the sound environment of nursing units. This research sought to address this gap. Subjective evaluations were gathered using questionnaire surveys of 75 elderly residents and 30 nursing staff members in five nursing units of five nursing homes in Chongqing, China. Background noise level and reverberation time were measured in five empty bedrooms, five occupied bedrooms and five occupied nursing station areas, in five nursing units. The subjective evaluation results indicate that the residents stay in the nursing units for most of their waking hours. The residents and nursing staff had strong preferences for natural sounds, with the lowest perceptions of these in the nursing units. The background noise level in all the occupied bedrooms exceeded Chinese standards for waking and sleeping hours. Only 20% of the occupied nursing station areas were below the allowable noise level for recreation and fitness room during sleeping hours. The nursing station area was identified as the main source of noise in the unit during waking hours. The average background noise level of the occupied bedrooms was 3–12 dBA higher than that of the empty bedrooms during sleeping hours. Attention should be given to the implementation of noise specifications for sleeping hours. The reverberation time of the bedrooms was within the range of 0.44–0.68 s, and in the nursing station areas it was 0.63–1.54 s.

“…The often-problematic acoustic environments in restaurants, cafes and dining halls are examined by many researchers who tried to define acceptable and preferred ranges for various performance criteria, such as reverberation time and sound pressure levels. Rindel (2012a), Soyer and Houdet (1986), Astolfi and Filippi (2004), Kang (2006), Hodgson et al (2009), Battaglia (2014), Svensson et al (2014), Zelem et al (2015), Watson andDowney (2008), andTarlao et al (2021) investigated acoustics of eating establishments with measurements and questionnaires. In these studies, it is mentioned that a narrow range between 0.5 and 0.7 seconds of reverberation time has been found to provide acoustic comfort for customers (Battaglia 2014) and a reverberation time over 2 seconds can make users uncomfortable (Zelem et al 2015).…”

Psychoacoustic parameters are mostly used for determining the sound quality of mechanical sounds. They have also started to be used for evaluating soundscapes of open areas and enclosed spaces. This research aims to find out the relationship between the psychoacoustic parameters and acoustic comfort in non-acoustic enclosed public spaces, specifically in eating establishments. Both on-site measurements and laboratory listening tests were conducted for five eating establishments. During on-site measurements, a simultaneous questionnaire study was also carried out. Subjective and objective data were comparatively evaluated. Listening tests were based on auralizations with calibrated simulation models. This provided a research model, that allows control over the acoustic environment without having to make real changes in the physical elements of the eating establishments. The auralization sound files were presented to listening test participants with headphones and they evaluated soundscapes with different psychoacoustic properties. As results, better acoustic comfort was found to be related with higher sharpness, lower reverberation time, lower loudness and lower roughness values for the examined parameter ranges.

It becomes a node where people eat, socialize, work, reading or any celebrations (Hodgson et al, 2009).

All the time, caféis an essential partof our daily life -a node where people socialize, work, or even where they got their inspiration of idea. Lately, there been booming of adaptive reuse of heritage buildings to become caféalong the Jonker Street Malacca; each caféis various in size and theme. All these projects mainly to restore historical visual traits and focus on restoration through function change. Somehow, designers and planners always neglect the role of sound, which is very crucial element of our environment and daily lives whenmaking place making. Thus, this research is aimed to investigate and evaluate the level of the acoustical performance of adaptive reuse buildings at Jonker Street Malacca. Analytical method on a computational modelling of cafe will be used for this research which involved acoustical evaluation (noise level, reverberation time, Speech Transmission Index) simulation. Few cafe types were modeled in a room acoustic simulation application with a manipulated variable of volume, sizes and ceiling height. Basic sound field properties of typical cafe types are highlighted based on the finding of the study. The generated index from variables hopefully could be used to design and evaluate caféspecific acoustic environments in the future.
