As other posters have mentioned, one big drawback of the Dyson Airblade (stand alone unit) is that it's loud. 90 dBA loud [1]. I've never seen more than two Airblades in one restroom, with this combo unit, there could be double that number. That could lead to an unpleasant environment for guests of the establishment and potential OSHA violations for employees.
From using it, it appears to me that most of the noise is caused by the turbulence of the high-speed airflow interacting with hands and the enclosure (Fullerton's paper comes to the same conclusion). In that case, all you can really do to reduce the noise is reduce the flow speed, which reduces the effectiveness of the dyer action.

So now whenever we go, we put a "do not use - baby is feeding" note on the hand-dryer. It's not a drop-in replacement for towels or normal air-dryers by any means.

Just as The Wiggles showed that there is money in adapting adult music for kids, maybe there is money to be made by taking children into account in the design of public facilities? Venues that are frequented by families (shopping centres, child care centres, schools, ...) might be prepared to pay for a line of appliances that don't make life unpleasant for their customers?

He replied they had, but there was a strong perception amongst the public that noise equals power, and therefore a quiet vacuum wasn't sucking very much. Wonder if he's carried the same sentiment over to other products Completely unrelated Dyson trivia - Dyson manufactured a washing machine for a short while; the white and purple CR01
