    • Taiwan has a rapidly growing elderly population, one of the serious issues among elderly in Taiwan is dementia. Dementia is an incurable and irreversible syndrome that causes progressive impairment of cognitive functions, behavior and psychology of its victims. Therefore, the need for long-term care facilities has also increased. For elderly individuals, acoustic comfort is as important as thermal and visual comfort. The purpose of this research was to study the preference for acoustic comfort through a listening evaluation with individuals that are both inexperienced and experienced with caring for dementia patient. The listening evaluation was based on 20 sound samples recorded in two Taiwanese long-term care facilities and a university dormitory.
    From the recordings, 66 architectural students and 19 caregivers from a dementia care unit participated in the listening evaluation. A semantic differential scale questionnaire with 11 pairs of sound qualities was used. The results demonstrated that all respondents from both groups had a negative impression of the water pump sound because of its noisy and harsh sound qualities. Live percussive music was considered noisy and agitating by 97% of the respondents from the student group, but the caregivers group regarded it positively based on meaningful and friendly qualities. Birds chirping was recognized by the students and caregivers as the most comfortable sounds, associated with a bright and friendly impression in addition to meaningful qualities from the caregivers group. A silent dormitory room was considered the preferred sound in both groups with positive impressions and was associated with quiet and calming qualities by the student group, and comfort and calming by the caregivers group. A grandmother arguing with a talking loud sound sample was considered noisy, discomforting and agitating by the caregivers group. Acoustic comfort did not merely depend on tonal character of the sound itself, but also on the aural contextual satisfaction. These findings suggest that enhancing natural sounds and silence as well as mitigating man-made noises are key to achieving optimal acoustic comfort in a living environment for people with dementia.
