Here are some links to some software that I’ve written that may be useful in the field of audiology. All the software linked on this page run on Windows computers and are freely available under an MIT/X11 license. If you find errors in the programmes, I’d be happy if you would tell me via info(at)software.erikwitte.com
The audiogram drawer is a simple program that draws audiograms according to Swedish standard. The software can also do calculations of pure tone averages and some other useful stuff. In addition, the software can simulate hearing loss on a sound file of your own, so anyone with normal hearing can listen to what different sounds may sound like for people with various degrees of hearing loss.
The ’Speech in noise mixer’ software is created to make it easy to mix recordings of speech with noise in order to create stimuli for audiological speech in noise tests.
The audiometry simulator is a software intended to be used for practicing audiometry. As of now, it works with standard pure tone audiometry. The software does not contain ready made patients, but instead simulates new unique patients for each session. Except for some initial settings, it is not possible to know in advance the hearing status of the (simulated) patient being measured. After the session ends, an audiogram containing the true thresholds will be created and displayed in a folder automatically (as that folder might be a bit tricky to find otherwise). Good luck practicing your audiometry skills!
The Audiologic Sound Editor is a simple audio editing software which will contain some common functionality used within the field of audiology. It contains functions that can be used to create stimuli for interrupted speech tests, to concatenate and mix test list recordings, and to optimize difficulty levels and phonemic balance across different test lists.
The Code generator is a software that can be used to create a set of unique random codes, with an adjustable degree of maximum similarity. It is suitable for use in research projects to create id-codes for participants.
