I am working on a classification of Asthma Based on the database. I was searching on internet to find a database about it. However, I couldn't find appropriate database.
I have searched Google for mp3 and wav file types AND asthma, but received no results. A Scholar search for "Asthma sounds database" also gives no results. It looks like the time is right for you to make such a reference database. It will be useful.
I have equally not found any of such database on asthma sounds. It will be a wonderful initiative if your project will be successful of which I am keenly wishing for. Best regards
you may want to contact Hans Pasterkamp who has compiled sounds and nomenclature. See e.g. here: http://erj.ersjournals.com/search/author1%3AHans%2BPasterkamp
