Screening audiometry routine

Like slightly troubling obsessives, we have a well-polished routine for conducting hearing tests for clients as part of our audiometry provision.

Before the big day

Before the day, or days, you'll be sent a schedule of appointments, giving you the exact times for each test in this batch, along with our arrival and departure times at the site. Before the day itself, we can help rejig it if needed to avoid things like lunch breaks. We cover all shifts so will make sure hearing test appointments are provided for everyone no matter what shifts they are working.

On the day

We shall arrive and ask the contact to point us in the right direction for the location to park the hearing test van. Bear in mind that size-wise it is a long wheelbase tranny van, so not too huge, with the attendees entering and leaving via the rear doors so it can't be parked too tight back against a wall. Other than a bit of space to squeeze it in, the two main considerations are:

  1. Availability of a power supply. The van needs a single standard 240v supply and carries about 25m of cable. It can plug into normal three pin indoor sockets or into the blue round external supply connections. 
     
  2. Located somewhere reasonably quiet. Not under any big extraction systems which will rumble away, and preferably away from idling trucks or busy roads.

We will set up, levelling it up if needed, and if it's winter giving the back door a quick sluice with water to clean any road muck off, then:

  1. We measure the noise levels in the booth and record them. This is a check that the van's location is OK and if the levels are a little high we will work with the client to identify any possibilities for a quieter spot.
     
  2. A test is done of the equipment to make sure the calibration has remained accurate and all connections and cables are working as they should be. This is recorded in the batch of tests for that day so we can provide it in the future if needed (for example, for insurers).
     
  3. Pre-test questionnaires are placed in the waiting room, door opened and a welcoming smile adhered to our faces. If Adam is doing your testing he has been told his 'welcoming smile' looks like someone who has been desperate for a poo for three days, but it's the best he can do.
     
  4. Each attendee comes in and completes the hearing health history questionnaire in the waiting room.
     
  5. They then come in and we go through it with them. If there are any pertinent points or bits of information on the questionnaire we note it in the comments section of the audiogram, (the document which will contain the results of the test and which goes to the client). 
     
  6. Next is a visual check of their ears with an otoscope - the small torch thing we poke down their ears. This is to check the ears are clear, look how healthy the ear drum is, and also see if there are any signs of infection. Looking for anything which may impact on the audiometry results.
     
  7. Finally, the hearing test itself - the 'hear beeps and press a button' bit. This is seven frequencies per ear and takes about eight minutes. It's the same as many people probably had at school except they don't get a lollipop afterwards this time.
     
  8. Then we get them out of the booth, wipe the headphones down with antibacterial wipes, and then print their result out.
     
  9. We explain the result to them, showing how they compare to normal standards for their age and also how they compare to any previous results of theirs. We then give them a copy of the result and their questionnaire to take away with them.
     
  10. Then we send them out, shout 'next' and the next victim shuffles in.

Once the last test appointment has gone, we will pack up, say t'ra and be off. It takes about half an hour after the last appointment to pack up.

Afterwards

The data is automatically synchronised back to the office which helps ensure it is always backed up, and also that it does not need to be emailed, eliminating risk.

The paper audiograms are dropped off at the office. They will be scanned into PDFs and then appended to the audiometry report. That PDF document is then emailed over and contains the full report and all results.
