Sound level around seriously ill patients "like a busy road"

17.09.2012
Seriously ill patients in intensive care units are being cared for in environments with sound levels more than 20 dB higher than the WHO’s recommendations. This is shown by a study carried out in partnership between the University of Gothenburg, Sweden and the University of Borås, Sweden.
In the study, the researchers registered sound levels around 13 seriously ill patients cared for in the intensive care unit at Södra Älvsborg Hospital over a 24-hour period. The study shows that the sound levels around seriously ill patients were on average between 51 and 55 dB. This is comparable with a busy road.

For the greater part of the 24 hours, between 70 and 90 per cent of the time, the sound level was above 55 dB – in addition, there were a number of short sound bursts above 100 dB.

When the patients were interviewed about their experiences of the surrounding sounds, they recalled both positive and negative experiences. Positive experiences included, for example, the sound of the staff talking quietly between themselves or providing information on ongoing treatment.

"Sounds perceived as frightening were uncontrollable sounds from, for example, alarms, and sounds from seriously ill fellow patients, and treatments and examinations. One patient also described how the sounds around him had entered into his dreams and hallucinations,"says Lotta Johansson, researcher at the Sahlgrenska Academy, University of Gothenburg, who led the study.
The sound levels found by the study are slightly lower than those measured by previous studies, but still significantly higher than the 30 dB recommended by the WHO for patient rooms in hospitals.

“The interesting thing is that what the patients considered most disturbing was unknown and uncontrollable sounds rather than the generally high sound level. This shows that we must take further measures to create healing care environments with better conditions for sleep and recovery for seriously ill patients,” explains Lotta Johansson.

The study “The sound environment in an ICU patient room – A content analysis of sound levels and patient experiences” was published in the journal Intensive and Critical Care Nursing. It is a preliminary study for a larger project in which the researchers will study in more depth and from a longer perspective how the physical environment affects seriously ill patients.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
