NOISE LEVELS ON THE PAEDIATRIC HIGH DEPENDENCY UNITÂ
Abstract
Background
Previous studies have shown that WHO noise level guidelines are frequently exceeded on intensive care ward (1)
Objectives
To measure noise levels and acivity on a Paediatric High Dependency Unit.
Methods
Sound levels (in decibel) were measured over 4 x 2-hour periods (two mornings and two evenings) using the SLM24TK digital sound level meter. Ward activity was also documented.
Results
Noise levels shown in table. Conversation was the largest single contributor for frequency and noise level. Noise levels exceeded guidelines on all days
| in dB | max | min | Average | |
| DAY 1 AM | 85.1 | 32.2 | 56.3 | |
| DAY 2 AM | 89.1 | 36.6 | 58.6 | |
| DAY 3 PM | 91.2 |
| 60.4 | |
| DAY 3 PM | 83.6 | 35.0 | 57.5 | |
| Average | 87.3 | 34.0 | 58.5 |
Conclusion
Average sound levels were above WHO guidelines and recommended sound levels for sleep on all days. Peak noise was always above 80dB, a workplace safety limitation. Although further research is necessary, simple interventions may already be appropriate. These would include cost-effective solutions such as staff education and use of headphones, as used in other studies.
