Mobile audiometric testing units
The Noise Chap can offer audiometric testing in our properly lovely purpose-built mobile screening units which can park on the site and operate off a single standard 240v power supply. They are right nice, with a separate waiting room where the pre-testing questionnaire can be completed, then a main testing room with a built-in audiometry booth. They are based on big black vans and look like the kind of things which should be lurking round the back of a care home at night when a room has 'suddenly become available'.
Alternatively, if the client prefers we can do the hearing tests in a quiet space on the client's site which can be an office, conference room, medical room, etc. This has proved useful in the past, for example at a high-risk food production site where instead of employees coming out of the clean environment to go to and from the testing unit we stationed the screening equipment in the first aid room bang in the middle of the site meaning employees didn't have to change clothes to attend their test.
The choice of testing location is up to the client as best suits them, and needs to take into account ambient noise levels present for each.
Where spirometry is being done, this will be done in the same room as the audiometric testing.
We do not put air conditioning in the audiometry units. "Why not after this summer?" I hear you cry.
Aircon in mobile audiometry units is pretty much just a gimmick as the one thing you can never do with it is actually turn it on during a series of hearing tests as all aircon units make too much noise. If a technician ever does a hearing test with an air conditioning unit turned on then they need a good slap as they've taken a unit where thousands of pounds have been spent to reduce noise levels, then gone and added noise to it again.
From a personal stand-point as the person responsible for the vehicle, roof mounted a/c is a right pain in the bum! It always leaks at some point and you end up with it raining in or water getting into the roof insulation. Then the bolts work loose over time - imagine the heart-lurching moment of discovering one of your units on the M5 with the a/c unit worked loose and now hanging over the edge of the roof, kept there by nothing more than the power cable and how close that could have been to disaster. That happened once. And not forgetting the one employee who took a trailer with roof mounted a/c under a low bridge and destroyed the a/c unit.
So now, no a/c. Technicians shouldn't use it when testing anyway, putting holes in the roof always causes problems, and it's just an unnecessary risk which is not good for my blood pressure. Aside from unusually hot periods it's not necessary anyway - we live in the UK rather than Greece no matter how much we wish otherwise in the middle of a grey February.
Access for wheelchairs or impaired mobility
There are two to three steps up into the audiometric testing van meaning these have to be climbed to enter it. In the testing room, even though the interior takes the full width of the van, the gap between the walls and the desk or booth is too small to fit a wheelchair through, with no space to make it wider. The width of the van also means the door from the waiting room into the audiometry testing room is narrower than a standard door, and audiometry booths themselves are fairly narrow.
In cases where a wheelchair user needs a test we recommend scheduling them at the end of the session and we will remove the necessary equipment from the van and set it up in an office or meeting room and do the test there.
Please allow half an hour between the last hearing test and this one to give time for setting the equipment up.
