As part of my MSc dissertation in critical care at Cardiff University, I aimed to reduce noise levels on an intensive care unit, to enhance sleep quality and reduce the incidence of delirium. A Pulsar SafeEar Noise Warning Sign was placed within each individual bed space, following the activation of the warning signs, quiet time noise reduced by 3 dBA and night time noise reduced by 4 dBA. This reduction in noise levels also reduced the incidence of delirium by 8.1% from the previous year. These results highlight the importance of these visual prompts to try and remind staff and visitors to reduce noise levels.

I had initial difficulties with the data loggers, which was resolved by a senior member of Pulsar driving over 6 hours to sort the problem…….embarrassingly caused our computer system!!!! The customer care we received from Pulsar was excellent, everybody in the team we spoke to was very professional and helpful and went way and beyond what was expected to resolve our initial ‘technical glitch’. Simon, the sales manager was also pivotal in helping me understand the logarithmic decibel scale.

I can not thank the team at Pulsar enough.
