How design affeCts wellbeing
The architectural and functional design of hospitals can improve people's wellbeing. Hospital design must ensure patient services can be provided by staff. In the long-term, it can also promote patient safety and care quality, reduce care costs, lower operating and construction costs as well as provide other significant business advantages.
Nowadays there is growing awareness amongst healthcare managers and architects about the importance of design in a healing environment. The environment should help staff perform to the absolute best of their ability and help patients cope with the considerable stress that illness involves. Supportive Healthcare Design is inevitably holistic and evidence-based: more than 700 research projects have analysed the effects of colour, lighting, temperature and sound on the wellbeing of patients, visitors and healthcare staff. Several investigations and research projects have pointed out clear links between sound levels and the quality of care.
Care about sound
When people think of a place to recuperate from illness or medical treatment, most visualize places that are quiet and peaceful. This is in stark contrast to the typical modern hospital, where noise from beepers, alarms, equipment, telephones, voices and more fill the normal sound environment. Hospital noise - one of the biggest complaints of patients - should no longer be ignored. Especially as a good sound environment becomes indispensable in the context of intense, accurate communication while applying stricter rules regarding patient privacy and patient data security.
Ecophon's system solutions are developed to combine acoustic, aesthetic, hygienic and other relevant requirements. The available solutions are not only decisive for the economics of a healthcare facility but also for recovery and personal health.

Hospital noise is not only a primary cause of patient dissatisfaction at most hospitals. It can negatively impact patient outcomes, cause sleep deprivation and prolong the healing process. risk to Patient outComes
Much research has documented the negative effects of hospital noise on patient outcomes. Several studies on infants in natal intensive care units, for instance, show that higher noise levels increase the need for oxygen support therapy, elevate blood pressure, increase heart and respiration rate, as well as negatively affect sleep1-3.
Patients exposed to continuous extraneous noise can also experience memory alteration, increased agitation, less pain tolerance and feelings of isolation. Noise has been shown to contribute to patient falls, cause confusion and result in increased medication and use of restraint. These environmentally generated symptoms are often medicated or otherwise treated in ways unrelated to their cause. In addition, hospital noise increases a patient's anxiety and decreases his confidence in the clinical competence of the staff, thus bringing into question the service HosPital noise:

main Cause of sleeP dePrivation
Hospital noise is a stress factor that can cause sleep deprivation among patients. Research on adults and children clearly shows that noise is a major cause of waking and of sleep deprivation. When a person is deprived of sleep, there is a risk that this may be associated with a diminished protein synthesis and immune function, both important aspects of healing5.
What causes disturbance to patients' sleep? According to a Finnish study that sought to clarify the sleep disturbance factors of patients, the cause is the hospital environment itself. Data from 177 patients at the Central Hospital of Northern Carelia's two medical and two surgical wards was collected. The results indicated that hospital environment factors (noise from other patients, equipment, working nurses, and general hospital noise) were regarded as the main causes of sleep disturbance. In fact, 80% of patients regarded these factors as the cause of disturbed sleep. As a comparison, only about half of these patients the cost of readmitting a

Studies conducted by sleep researcher and medical doctor Sören Berg of the University of Lund (Sweden) confirm that patients' sleep quality is improved when Ecophon sound- absorbing ceilings are used in the wards8. Dr. Berg's findings confirm that the sound-absorbing properties of a room affects a patient's ability to maintain satisfactory sleep quality even when subjected to noise. In one study, 12 healthy people slept several nights in a ward in which the ceiling tiles were altered beetween those with sound-absorbing properties and others with sound-reflecting properties. Various environmental sounds were played The number of sound-induced instances of waking dropped from during the night. Objective sleep quality was assessed by 42% to 25% when the ceiling was electroencephalograph (EEG).

Not only is healthcare a physically and emotionally demanding service to deliver. Healthcare staff and hospital employees spend more time in the facilities than patients do. Healthcare design can help increase employee satisfaction and commitment. After all, the design of a healthcare facility tells a story about that premise and communicates a great deal about management's concern for caregivers. stress, burnout and turnover
There is evidence that hospital employees perceive high levels of sound as stress-inducing1-3. One such study, for instance, looked at the correlation between stress among registered nurses and hospital noise in a tertiary care paediatric intensive care unit. Eleven nurse volunteers took part in the study and were observed for a three-hour period of patient care. Heart rate and sound level were recorded continuously; saliva samples and stress/annoyance ratings were collected every 30 minutes. Variables assessed as potential confounders were the number of years of nursing experience, caffeine intake, patients' paediatric risk of mortality HosPital noise:

levels significantly predicted higher heart rates. Higher average sound levels were also predictive of greater subjective stress and annoyance. Accordingly, the study reports that noise was shown to correlate with several measures of stress including tachycardia and annoyance ratings.
Other studies show that people who work long shifts in noisy environments, day in and day out, report effects from exhaustion to burnout, depression, and irritability expressed at home. Interfering and distracting sounds have been shown to contribute to medical and nursing errors. Importantly, noise-induced stress in nurses correlates with reported emotional exhaustion or burnout4-5.

Care about sound™
According to researchers at Johns Hopkins, noise levels in hospitals throughout the world have been increasing by about 0.4 decibels per year since 1960. Their findings indicate that average daytime hospital sound levels on a global basis have risen from 57 to 72 dB since 1960 and that hospital noise at night has gone up from 42 decibels to 60 dBs. According to the report from Johns Hopkins, current sound levels are now sufficiently high to be a concern to patient safety. about tHe study
The sound pressure levels in various units of the Johns Hopkins Hospital were monitored using a precision sound level meter, producing sound levels as a function of location, time of day and frequency. Other highlights from the study include: • The measurements vary little between different types of hospitals, a growing
indicating the problem is widespread, • Much hospital noise falls into the human speech frequency range, making oral communication difficult. This can force doctors and nurses to speak louder to be heard, further boosting noise levels, • Measurements indicated that noise levels remained high throughout the day and night.
Case: noise reduCtion strategies imPlemented
Initially, two improvements helped to lower noise levels in several patient care areas. Firstly, staff were equipped with hands-free personal communicators and the regularity of overhead paging dropped to about once an hour, from once every five minutes. Secondly, as many areas lacked sound-absorbing ceiling tiles, researchers wrapped fibreglass insulation inside anti-bacterial fabric and mounted the sound-absorbers onto ceilings and walls in an oncology unit. This reduced sound reverberation by a factor of almost three. After a number of weeks, the researchers' own sound-absorbers were replaced with solutions from Ecophon.

Care about sound™
The sound environment of modern hospitals typically contains very high noise levels, for example: • Noise from alarms and certain equipment exceed 90 dB, which is comparable to walking next to a busy street when a large lorry passes. A study in a NICU measured peak levels once per minute and found that 31 percent of peaks exceed 90 dB1.
• Noise peaks in hospitals can be extraordinarily loud. A recent study recorded 113 dB during shift changes at a large hospital,which is painful and can even be harmful. This can be comparedto a sports event2.
• Noises from surgical drills, saws and other equipment in the operating theatre are in the range of 100 dB to 110 dB(comparable to a lawnmower) and presents a significant risk for noise-induced hearing loss3-5.
Note: In judging these levels, it is worth noting that the decibel scale is logarithmic; each 10 dB increase represents approximately a doubling of the perceived sound level. A 60 dB sound, accordingly, is perceived as roughly four times as loud as a 40 dB sound.
reasons for tHe noise
A research team from The Center for Health Design recently looked at more than 130 references focusing on noise in hospitals in the published tHe noise gets
studies. They suggest two general reasons why hospitals are excessively noisy6. First, the noise sources are numerous and they are loud. Second, the surfaces in hospitals (floors, walls and ceilings) are usually hard and reflect sound rather than absorb it. The design of many modern hospitals thus actually amplifies noise. For hygienic reasons, hospitals are built with hard, easy-to-clean surfaces. No carpets or sound-muffling panels are used. These hard surfaces affect sound as a mirror affects light. They simply reflect the sound. If sound is free to bounce around, it will do just that.
sPeaking above tHe noise
A large proportion of hospital noise falls within the frequency range for human speech. Hospital staff often need to express themselves loudly to compete with the background noise from medical equipment, paging systems, mechanical building elements, etc, in order to make themselves heard. Due to this, the sound level inceases even more; this is referred to as the Lombard Effect.

sound environment assessment
To reduce hospital noise and improve the sound environment, standards have to be set that are just as stringent as all others relating to patient safety. An assessment of the sound environment provides the basis for this. Many facility areas are dynamic, having peak periods of activity and noise. It is therefore important to profile the facility and list its different sound and functional zones. Identification of noise sources is another important aspect of managing the sound environment. However, many noise sources are not easy to resolve, such as mechanical and building noise. Defining the desired sound environment in a sound policy as well as involving acoustical engineers, architects and building experts is the best way of addressing the planning of renovations as well as the design of new facilities.
ensuring quality sound environments
In its key recommendations for reducing hospital noise1, the Center for Health Design states that environmental interventions that have proven particularly effective for reducing noise and improving acoustics in hospital settings include: • Installation of high-performance, sound-absorbing ceiling tiles • Elimination or reduction of noise sources (for example, adopting a noise-free paging system) the right acoustic ceiling
• Provision of single-bed rather than multibedrooms reduces noise by several
decibels. the sound-absorbing

to rest and staff to focus on the tasks at hand.
room acoustics: In rooms with hard surfaces, sounds build up and
increase the general noise level. The use of sound-absorbing material reduces
noise levels and increases comfort. In larger rooms, the amount of sound
absorption will also affect sound propagation in the room and from the room
to other areas as well as vice versa.

The quantity and placement of sound-absorbing material is the key factor for good room acoustics in healthcare facilities. Room acoustics relate to the sound environment in a restricted space. The most common measurement is reverberation time, but in many instances it is of even greater importance to measure the reduction in sound level. In rooms where transmission and communication of information is of great importance, other measurements can be used to gauge speech intelligibility or privacy. sPeeCH PrivaCy
Speech privacy is of increasing importance in everyday life, including
healthcare facilities. The need to measure and rate a room's performance
is driven by both patient demand for the respect of privacy and by
regulations. According to ISO, speech privacy is conversation that is not
intelligible to casual listeners. It is defined by the Articulation Index (AI) and can be measured objectively.
When it comes to minimising sound disturbance between people and/or different areas, room layout is very important. Speech is the most good room
disturbing factor because it is very difficult to 'tune out' and distracts people more due to the instict to try to hear what is being said. However, in healthcare premises, individuals must be given as much privacy as possible. In order to prevent sound from being reflected and propagated via the ceiling, it is crucial that the acoustic ceiling has excellent sound absorption properties across the whole frequency range.
baCkground noise level
This is weighted to correspond to the human ear, dB(A). The WHO
recommends that the equivalent sound level should not exceed 35dB in
areas where patients are being treated, observed or resting. Momentary
sound during the night should not exceed 45dB. An effective acoustic
ceiling reduces background noise.
This indicates the extent to which a listener understands what is being
said by the speaker. Various methods are used to quantify speech
intelligibility. Speech intelligibility is directly dependent on the level
of background noise, reverberation time and the shape of the room.
Different methods are used to evaluate speech intelligibility. Effective
acoustic ceilings improve speech intelligibility.
sound Pressure level
High noise levels due to activities or equipment are often the main
disturbance in many surroundings. These make communication difficult
and increase stress and the feeling of discomfort. To decrease the sound
pressure level in an efficient manner it is important to use acoustical
products with as high sound absorbing properties as possible.
This indicates the time needed for a single sound to decrease by an
interval of 60 dB. A short reverberation time is often considered to
provide a more home-like acoustic environment with a lower echo. In
healthcare buildings, room surfaces are often made from hard, sound-
reflecting materials; these have a negative impact on room acoustics.
A short reverberation time can be achieved by using sound-absorbing
ceilings or wall panels.
