Hospital noise levels growing worse, say researchers Noise levels in hospitals are getting worse, research suggests.
Anyone who has ever stayed overnight in a hospital will know how difficult it can be to sleep, surrounded by staff, machinery, trolleys and telephones.
In the UK, 40% of hospital patients are bothered by noise at night, according to in-patient surveys.
But it's not only the patients' wellbeing that may be affected - high noise levels can also have an impact on staff performance and burnout rates.
Researchers from King's College London say noise levels in intensive care - where the most vulnerable patients are looked after - regularly exceed 100 decibels. BBC News
