完成醫院及圖書館公共服務區室內音量測定並參考國外有關公共場所室內音量測定指標及方法，研擬適合我國公共場所室內音量建議值包括：1.進行圖書館室內音量測定10處、醫院公共場所室內音量測定30處，醫院ＬAeq(hr)符合60dB(A)達46%，L日符合60dB(A)達42%，圖書館ＬAeq(hr)符合50dB(A)佔54%，L日符合50dB(A)佔52%，全國北、中、南、東各區醫院之L日音量比較，以中部地區最吵。2. 建議醫院的室內音量LAeq(1hr)為60dB(A) ，圖書館的室內音量LAeq(1hr)為50dB(A)，醫院分級：特級(安靜)：音量<50 dB(A)、一級(普)：50 dB(A) ≦音量<60 dB(A)、二級(需改善)：音量≧60 dB(A)，圖書館分級：特級(安靜)：音量<45 dB(A)、一級(普)：45 dB(A) ≦音量<50 dB(A)、二級(需改善)：音量≧50 dB(A)。
完成資料蒐集、實地現勘調查，瞭解醫院及圖書館室內易發生噪音源分布情形：1.醫院移動音源－輪椅、病床、病歷推車、喧嘩聲，交談聲、手機鈴聲、小孩喧鬧、護士小姐奔跑聲、醫護人員叫喊病患聲；固定音源－飲水機、室內空調(機)設備、掛號處印表機、叫號聲、廣播及電視、電梯到樓提示聲、醫護人員會議室和護理站。2.圖書館移動音源－交談聲、手機震動(鈴)聲、書報上架推車、走路聲；固定音源－搬動桌椅、開關門聲、冷氣空調、廁所、飲水機、翻報聲。3.八家署立醫院Leq，LF（20 Hz至200 Hz）低頻噪音值40.7
The Study of this project include to develop recommended values and the grading system for indoor noise quality at hospitals and libraries suitable for the situation of our country, to analyze and investigate the distribution of noise sources easily occurred inside hospitals and libraries and demand self-improvement by the management of respective hospitals and libraries, and to formulate a model of the “Self-regulated Noise Improvement Method for Hospitals and Libraries”, for the management of hospitals and libraries to follow in their efforts to improve their noise situation.
The achievements of this project are as follows:Completing indoor noise measurement for hospitals and libraries and developing recommended values of indoor noises for public places suitable for the situation of our country, making reference of the measurement indicators and methods on indoor noises for public places adopted by foreign countries, during which the work conducted include: 1) measurement of indoor noises for hospitals on 30 locations and for libraries on 10 locations, of which the results showed that for hospitals, 46% comply withＬAeq(hr)=60dB(A) and 42% comply with L日=60dB(A) while for libraries, 54% comply withＬAeq(hr)=50dB(A) and 52% comply with L日=50dB(A). As far as L日 is concerned, in comparison among hospitals in northern, central, southern and eastern areas, those in the central area are noisiest; 2) recommendation of indoor noise limits for hospitals at ＬAeq(hr)=60dB(A) and for libraries at ＬAeq(hr)=50 dB(A). The grades on noise quality recommended for hospitals: premium grade (quiet) – noise level < 50 dB(A), first grade (moderate) – 50 dB(A) ≦ noise level < 60 dB(A), and second grade (improvement needed) – noise level ≧ 60 dB(A); for libraries are: premium grade (quiet) – noise level < 45 dB(A), first grade (moderate) – 45 dB(A) ≦ noise level < 50 dB(A), and second grade (improvement needed) – noise level ≧ 50 dB(A);.
Completing data collection and field investigations, as well as holding consulting meetings, to determine the distribution of noise sources easily occurred inside hospitals and libraries, during which the work conducted include: 1) identifying moving noise sources at hospitals as being wheelchairs, hospital beds, medical record trolleys, uproarious noises, talking noises, cellphone rings, kids playing, nurses running, medical professionals calling for patients, and fixed noise sources as being drinking machines, interior air conditioners, printers at registration offices, number calling, paging and television, elevator arrival reminders, medical professionals meeting rooms and nursing stations; 2) identifying moving noise sources at libraries as being talking noises, cellphone vibrations (rings), book trolleys and walking noises, and fixed noise sources as being moving of desks/chairs, opening/closing of doors, air conditioners, restrooms, drinking machines and turning pages of newspapers; 3) measuring the low frequency noise levels (20 ~ 200 Hz, Leq，LF) at the 8 DOH hospitals as between 40.7 and 49.1 dB(A), which not comply with the noise control standards; 4) measuring the low frequency noise levels (20 ~ 200 Hz, Leq，LF) at the 4 libraries in University as between 35.5 and 39.6 dB(A), which comply with the noise control standards; 5) identifying the most noisy departments at hospitals as being the Department of Laboratory Medicine, the Department of Traditional Chinese Medicine, and the Department of Pharmacy.
Standards and related regulations on indoor noises are limited overseas, only WHO, ISO, the UK and New Zealand have established recommended standards for indoor noises. Currently, we have no standards and regulations on indoor noises in our country and it is hoped that recommended standards for indoor noises can be established through the implementation of this Study.
