The World Health Organisation (WHO) recommends an average sound level of 30 dBA in general hospital areas, however, the report ‘Noise in the ICU’ showed levels of 65-83 decibels (dB) to be the average noise level. A 2005 study conducted in the United States also found that some levels throughout Johns Hopkins Hospital, one of the top hospitals in the country, were on average at least 20 dBA louder than the WHO recommendations. It exceeded the average conversation speech level of 45 to 50 dBA, which signalled that patient care teams were finding it difficult to communicate without having to raise their voices.
Poor acoustics can contribute to poor health outcomes, through increased disturbance and intrusion; but also, mainly through its effects on communication. Patients withhold important or perhaps crucial health information or do not state their true feelings where they believe others will hear their conversations.
Avenue Interior Systems noise solutions are aesthetically pleasing and acoustically sound. We can custom design solutions for hospitals that are easy to clean to minimise the chance of patient infection.
