Ecophon Acoustic Bulletin

Evidence Based Hospital Design (EBD) is a new field that guides health care construction. Research indicates that well-designed physical settings play an important role in helping hospitals to support patients healing and making hospitals better places for staff to work. The findings support the importance of improving a range of design characteristics or interventions, including good acoustic environments, nature distractions and daylight.

The Building Acoustics Group of the UK's Institute of Acoustics has organised a meeting in Manchester on 16th June 2009. Entitled "Acoustics in Healthcare Environments", it will be held at the Victioria & Albert Hotel, and will discuss Key Issues relating to exactly how environmental acoustics affect healthcare outcomes.

It is of utmost importance that a patient is able to rest and sleep, but a Swedish study, conducted in a neurological intensive care unit, shows that is easier said than done.

Measurements were made over five days and showed average LAeq values of 53-58 dB, depending on time of day. But analysing equivalent sound pressure levels is not enough. It is also essential to analyse the occurrence and length of restorative periods, i.e. quieter periods where the noise levels is not assumed to disturb the patient’s sleep. The study shows that restorative periods last for only about 10 minutes, which means that a resting or sleeping patient will be disturbed several times an hour.

In "Challenging Designs of Neonatal Intensive Care Units", Anne Marie Dazé Floyd, RN, MSN, CNS says:
A link has been established between exposure to constant room noise and loss in frequency and pattern discrimination essential to understanding the spoken word. Loss of an ability to discriminate speech can cause profound developmental delay by interfering with language acquisition.
In addition to the connection between noise levels and deficits in hearing discrimination, clear connections also exist between noise and physiological instability.

Nurse researchers have provided evidence that hospital critical care unit (CCU) noise may put patients at risk of sleep problems. The study, by M Topf and M Bookman at University of Colorado Health Sciences Center, goes on to say that technological advances in CCU's are contributing to this problem and that the results provide support for the hypothesis that CCU sound levels impact negatively on subjective sleep.

Birmingham Women's Hospital NHS Trust took part in a regional campaign to raise awareness of noise levels in Neonatal Units and the need to reduce them. Lead by Advanced Neonatal Nurse Practitioner Cheryl Lewis, the campaign highlighted the impact noise can have on babies, and included staff training, posters and badges, and the use of a Decibel Monitor in the Unit.

Neonatal Units can be very noisy places, with the amount of medical equipment, alarms, telephones and people's voices, and this can impact upon the babies' development.

The new HTM (Health Technical Memorandum) gives Design Criteria for Room Acoustics in UK Healthcare Premises.
The document's Executive Summary states "Noise can increase heart rate, blood pressure, respiration rate and even blood cholesterol levels. Good acoustic conditions improve patient privacy and dignity, and promote essential sleep patterns. Such conditions are key to healing"
Recently published, it requires acoustic treatment, usually ceilings, to be provided in all occupied areas, including corridors.
"The requirement is ...

The use of alarms in hospitals was discussed intensively during the two days session "Healthcare Acoustics & Speech Privacy".

A study presented by S. Okcu, College of Architecture, GaTech, states that a patient in an ICU can be surrounded by up to 33 different alarms from medical equipment. Not only are the alarms disturbing to the patients, they also make the task for the staff to detect and analyse them more demanding.

Ilene Bush-Vishniac
"The alarms are of utmost importance, but do we really need all these alarms?" This is a question asked by Dr. Busch-Vishniac, MacMaster University (formerly from Johns Hopkins University) who was one of the presenters at the conference. And the question is relevant; in nine out of ten times no action is taken when an alarm goes off, except for turning the alarm off.

Noise levels in hospitals are typically more than 15 dB(A) higher than target values given in guidelines (for example target values from WHO and the US Environmental Protection Agency). Furthermore, noise is often one of the top complaints from staff and patients. This is concluded in a review made by Hui Xie and Jian Kang at the University of Sheffield.

I am Tobias Angelbeck, Concept Developer for Acoustics in Health Care Premises, Ecophon Germany. I talked to Dr. Jo Solet – the clinical Instructor at the Harvard Medical School, Department of Psychiatry, Cambridge, MA (USA).

Right now she and her department are doing two researches.
One is a behavioural research project related to patients exposure to noise, with an outcome on measure of medical views.
The other is a virtual hospital in a neuroscience lab, studying how patients respond to specific real stimuli in a hospital environment.

Katrin Bergmark, Concept Developer - Healthcare, Ecophon Sweden.

This question formed the introduction to the overview of acoustic standards in Europe presented by Katrin Bergmark, Concept Developer at Ecophon in Sweden. Katrin talked about the current situation regarding sound in health care premises. Hospitals are often experienced as very noisy, leading to health effects on both patients and staff. In order to create a supporting sound environment we should aim to:
- secure privacy
- lower the noise levels
- facilitate good communication

And develop standards accordingly...

This morning at 09:20 the session called healthcare acoustics & speech privacy – international perspectives started. Chaired by William Cavanaugh , David Sykes and Kerstin Persson Waye, the session provided an overview of emerging policies around the world.

Some of the conclusions are that the development of acoustic standards and guidelines for Healthcare facilities is really accelerating. David Sykes of ASA highlighted several waves of technological, economical and social trends that are responsible for that.

Sound levels in Health care premises have increased dramatically over the years, negatively affecting patient recovery as well as staff performance. Ecophon has recently published a knowlegde booklet on the sound envrionment in Healthcare premises, called Care about Sound. It describes the current noisy situation, lists relevant research and demonstrates through cases how well planned sound environments benefit the patient care in the end. Starting with an international version in English, other languages are planned to follow later this year.

Hospitals are extremely noisy, and noise levels in most hospitals far exceed recommended guidelines. The high noise levels, as well as peak noise levels in hospitals, have serious impacts on patient and staff outcomes.

Research suggests that environmental interventions may be effective in reducing the noise levels in hospitals and improving the acoustical environment. Key interventions include a.o. installing high-performance sound-absorbing ceiling tiles.

These are just some of the conclusions from the recent paper called "Sound Control for Improved Outcomes in Healthcare Settings" by Anjali Joseph and Roger Ulrich (both Center for Health Systems and Design).
