A AB BS S T TR RA AC CT T O Ob bj je ec ct ti iv ve e: : This study was conducted for determining the factors that cause noise in an intensive care unit (ICU). M Ma at te er ri ia al l a an nd d M Me et th ho od ds s: : The research was designed as a prospective, non probabilistic sample method to determine the factors cause in ICU. Between May and July 2012, a total of 50 consecutive patients who were over 18 years and had open heart surgery at the Cardiovascular Surgery Intensive Care Unit (CVSICU), Maslak Acibadem Hospital (Istanbul, Turkey) two months period were included the study. The noise intensity was measured by a device detects sound waves between 30-130 decibel (dBA). R Re es su ul lt ts s: : Forty three patients of total fifty patients expressed the CVSICU was noisy. The daily mean noise intensity was measured in 67,42 dBA, at nights 64,76 dBA and 70,08 dBA at daytime. It was stated the most of the complaints about the noise was related to monitor alarms. The mean noise intensity due to the monitor alarms was measured in 101,7 dBA. Other causes of noise were listed as door and telephone rings, IV pumping noises and noise of the staff, respectively. C Co on nc cl lu us si io on n: : In this study; it was determined that ICU environment was noisy, monitor alarms were the main noise source and noise caused changes sleep habits of patients. In order to overcome these problems, it's suggested that technologies might be developed enable monitor alarms can be only heard by related staff, deck telephones may only be heard by health professionals via activating vibration systems and unnecessary communications should be avoided.

G Ge er re eç ç v ve e Y Yö ön nt te em ml le er r: : Araştırma, yoğun bakımda gürültüye neden olan faktörleri belirlemek amacıyla olasılıksız örneklem yöntemiyle prospektif olarak planlandı. Mayıs ve Haziran 2012, iki aylık süreyi kapsayan tarihlerde, Maslak Acıbadem Hastanesi Kalp Damar Cerrahisi Yoğun Bakım Ünitesi'nde (KVCYBÜ) (İstanbul/Türkiye) 18 yaş üzeri ve açık kalp ameliyatı olan 50 hasta çalışmaya dahil edildi. Gürültü şiddeti 30-130 desibel (dB) aralığındaki sesleri algılayan bir cihaz ile ölçüldü. B Bu ul lg gu ul la ar r: : Hastaların %86'sı yoğun bakım ortamının gürültülü olduğunu ifade etti. Günlük ortalama gürültü şiddeti 67,42 dB, gece 64.76 dB ve gündüz 70.08 dB olarak belirlendi. Gürültü yakınmalarının başında monitör alarmlarının geldiği saptandı. Bu nedenle ortaya çıkan gürültü şiddetinin 101.7 dB olduğu saptandı. Diğer gürültü nedenleri arasında sırasıyla kapı ve telefon sesleri, intravenöz pump sesleri ve çalışanların sesleri yer aldı. S So on nu uç ç: : Bu araştırmada yoğun bakımda gürültü gerçeğinin süregeldiği ve en önemli sorumlunun monitör alarmları olduğu, gürültünün hastaların uyku düzenini bozduğu belirlendi.

“…In intensive care units (ICUs), alarm‐sounding technological equipment, health team members and the patient's relatives are present (Terzi and Kaya, ), which together create a noisy environment (Khademi et al, ). Although various studies have investigated the effects of noise levels in health care organizations on patients (Akansel and Kaymakçı, ; Maidl‐Putz et al, ), studies investigating the effects of noise on nurses are limited (Ryherd et al, ; Lacerda Costa et al, ; Watson et al, ).…”

“…Noise manifests itself especially in places such as hospitals where human traffic is busy and technological tools and equipment are used. It is stated that people working in hospitals are exposed to 87 dB(A) noise on average per day (Elliott et al, ; Khademi et al, ; Lacerda Costa et al, ). This level has been reported as being even higher in special units such as ICUs in which staff work for more than 8 h daily (Maidl‐Putz et al, ).…”

Background Intensive care units (ICUs) are noisy environments, which may have negative psychological effects on nurses. Aims and objectives To investigate the effects of the noise level of ICUs on nurses' burnout, job satisfaction, anxiety, psychological symptoms and general psychopathology level. Design A descriptive and correlational study. Methods The study was conducted with 150 intensive care nurses. A Type 2250‐L Brüel & Kjær hand‐held sound level meter was used for noise measurement. A Nurse Information Form, the Maslach Burnout Inventory, Minnesora Satisfaction Questionnaire, Self‐Report Inventory and Symptom Checklist‐90 Revised were used for data collection. Results The highest levels of noise (71 dB(A) and above) were measured in the neonatal, neurology and cardiovascular surgery ICUs. It was observed that noise level affected extrinsic satisfaction (F = 3·704; p = 0·027) and trait anxiety (F = 3·868; p = 0·023) of nurses. Conclusions Noise levels in ICUs are well above the recommended levels, and this affects nurses' job satisfaction and anxiety levels. Relevance to clinical practice More studies on the effects of noise levels on the physical and mental states of nurses working in ICUs are needed. Increased quality of patient care can be achieved by providing healthy working conditions for nurses working in special units such as ICUs.

“…Noise, defined as unwanted sounds, could affect people both psychologically and physiologically [7].Noise also has been defined as an accidental sound wave without any rhythm or harmony which can interfere with hearing [8]. To quantify sound levels, the decibel, an arithmetically non-dimensional linear scale, defines measured sound pressure [9,10], in which sound is measured as the force per unit area that sound waves produce.…”

This study was undertaken to investigate and analyze noise pollution in a large Chinese governmental hospital’s medical intensive care unit and compare to the WHO guidelines.This cross-sectional study was conducted in a MICU at a public governmental teaching hospital in Fujian province between July and August of 2017. A WENSN® WS1361 Integrated Sound Level Meter (China) was used for continuous every five seconds one week noise levels recording. After this measurement, the decibel meter was used for recording different location of isolation rooms and open bays, including occupied and unoccupied patient, and recording sound events occurs in the ICU to identify sources of noise. Peak and average noise levels were obtained from the meter, and data were downloaded from the WS1361 into a laptop computer. The measured mean equivalent sound pressure levels (L) and standard Aeq deviation over one week period were 66.64±7.57 dB(A), with acute spikes reaching 119.7 dB(A), the average sound level for a 24 hour period in a work day was 68.03±5.07 dB(A). These are higher than the current daytime environmental noise limit of 40-45 decibels in China and WHO. Mean work day noise was significantly louder than weekend time, there was a significant difference in work days and weekend (t=16.85;P=0.000).There was a statistical difference between the day time and night time shifts (t=34.67;P=0.000). The isolation rooms were significantly quieter than the open-bay rooms(t=46.15; p=0.00), sound levels in the occupied and unoccupied rooms also had significant difference(t=17.26; P=0.000).Two types of noise resources, including twenty kinds sources were identified and measured, mean noise levels ranged from of 61.33 to 79.21 dB(A). This study shows noise levels in intensive care units were exceeded the recommended. The study of the influence of noise on patient and staff is needed, and noise reduction strategies must be conduct in ICU.
