iBad: In-Ear Biosignals Audio Database

A comprehensive database of 25 subjects in-ear physiological signals has been created by researcher Alexis Martin from the EERS-ÉTS Industrial Research Chair in In-Ear Technologies, and may be available in near future, for other researchers too. To request an update on the availability of such database, kindly email Prof. Voix

A free sample of the database, provided as a Matlab binary file, is available for download, and contains the following test conditions:

    1. A1, A2, A3, A4, A5 = apnea
    1. A6E, A7E = apnea after exercise
    1. NP = deep nose breathing
    1. NN = normal nose breathing
    1. NR = fast nose breathing
    1. NE = normal nose breathing after exercise
    1. BP = deep mouth breathing
    1. BN = normal mouth breathing
    1. BR = fast mouth breathing
    BE = normal mouth breathing after exercise

A scientific journal publication detailing the whole test procedure has been recently made available on IEEE Transactions on Biomedical Engineering . If interested to request access to the whole database, please fill the CRITIAS:DB request form.
