Hospitals, including emergency departments, are full of equipment that requires procedural or environment consideration as part of its use. Defibrillators require removal of flammable materials and gases. Portable X-ray machines can't be operated in close proximity to people other than the patient. Hypodermic injections require the injection site to be sterilised beforehand. Intravenous lines have to be clear of gas bubbles. ECGs and EEGs can pick up radio (EMF) interference.

So it's a bit nuts to insist that a piece of equipment must be operable in whatever ambient conditions exist without any adjustment to eliminate known sources of interference. Users will balance the operational constraints of the equipment against the value of it. If the equipment has great value then users will make considerable efforts to use it effectively.

Resapp has demonstrated on a number of occasions that ResappDx is capable of performing effectively in a reasonably noisy environment, so it's quite clear that we don't need complete silence. If silence were necessary then there is no way we could have obtained the results we have in the Australian studies.

Soundproof booths and other extreme measures are certainly not going to be necessary. A commonsense auditory survey of the surroundings to make a judgement about whether it's necessary to move, switch something off or something else should be all that's required. If there's a feature on the product that will warn when the ambient noise level is too high, that can only help.
