Localisation test - small angles

This test estimates how well you can tell where sounds are coming from. This is done by determining the angle at which you are able to tell if a sound source is located to your left or to your right. This test may be of interest to you if you have ever experienced problems locating a sound source, just from the sound alone.

  • This test should be conducted in a quiet environment. If you use hearing aids, you should remove them before taking this test.
  • You should not use the standard "built in" speakers of your computer for this test. This test relies on the use of a set of peripheral speakers, which should be positioned in the way described in point 2, above.
  • You will need to do this test using a fast internet connection (i.e. broadband). If you hear drop-outs (silent intervals) in the sound than the connection you are using is not fast enough to do this test.
  • This test focuses on sound localisation. This will provide you with an idea how well you can tell where sounds are coming from. However, it does not cover all aspects of hearing and can as such not be considered as a full hearing test or a medical diagnosis. To obtain a more detailed hearing assessment, please visit your GP and ask to be referred to an audiology or ENT department.
