Impact of a visual indicator on the noise level in an emergency medical dispatch centre - a pilot study

BMC Emergency Medicine, 2021
Background Noise levels are monitored in call centres. A maximum of 52 to 55 dB(A) is recommended in order to prevent adverse events. We aimed at assessing the noise level and the impact of a visual noise indicator on the ambient noise level in a French ...
