WhiteSound scrubber-dryers – the right choice for quiet cleaning in noise-sensitive environments.

Exposure to undesired loud and/or continuous sound1 is harmful to health and, even when it does not lead to permanent damage, can cause discomfort, fatigue and distraction. It is therefore important to also consider noise levels when choosing a scrubber-dryer.

Especially in quiet environments, the perception of noise may be amplified by contrast with the silence of the surroundings. Even sound pressure levels only just above the norm may cause discomfort for those present.

This is certainly the case in hospitals, nursing homes, schools and libraries – all environments in which a relaxed and undisturbed atmosphere is essential.

In many cases, cleaning activities in these places have to be carried out while people are present. They must therefore be done as quietly as possible.

Eureka professional scrubber-dryers are ideal for these situations, because they are specifically designed for use in different environments and adopt special solutions for noise-sensitive contexts.

Top-quality vacuum motors, special rubber wheels (anti-noise and non-marking), testing during the design phase to minimise the transmission of vibration through the machine body and, above all, Eureka’s unique WhiteSound silent cleaning technology all contribute to making these scrubber-dryers some of the quietest on the market
 

Eureka scrubber-dryers for hospitals, schools and noise-sensitive environments.

Thanks to their special design features, the most popular Eureka machines in hospitals, schools and other noise-sensitive environments are generally WhiteSound versions of the E51–E61–E71–E81 walk-behind scrubber-dryers, which boast a sound pressure level between 63 and 65 dB (A) as perceived by the operator.2, 3 As well as being extremely quiet, these machines deliver a high level of efficiency and are the ideal size to enter lifts and pass through doors.

1 -'Undesired sound' is the common definition of 'acoustic noise'. ‘Audible sound that causes disturbance, impairment or health damage’ is the more precise definition given by the European Environment Agency (Technical Report No 11/2010).

2 - Decibel dB(A). A unit of measurement for sound power or pressure. The symbol A represents the weighting curve used. Reference sound pressure levels include:

0 - 5 dB(A) Threshold of hearing 
30 - 40 dB(A) Library    
50 - 60 dB(A) Office       
70 - 80 dB(A) Conversation       
100 - 110 dB(A) Car horn       
115 - 120 dB(A) Pneumatic hammer          
> 130 dB(A) Threshold of pain

3 - Sound pressure measurements on Eureka machines are conducted according to ISO 3744 standard.
