WAI Database : Wideband Acoustic Immittance Database
WAI Database This webpage hosts a database for the WAI measures made on ears from infant, NICU infant, child, and adult subjects. It is funded by the National Institutes of Health, NIDCD, and hosted on a server at Smith College (PI Susan Voss, R15 DC014129-01). The goal of the database is to enable auditory researchers to share WAI measurements and combine analyses over multiple datasets.
PI_Info, Subjects, and Measurements. Our team is happy to help format thexse files if you simply email Susan Voss (svoss AT smith.edu). PI_Info: Generate a .csv file with columns that match the established WAI database table PI_Info, defined here PI_Info_Codebook. Note, there will be one row for one published article, or simply one row per submitted data set. Subject_Info: Generate a .csv (comma-separated-value) file with columns that match the established WAI database table Subjects, defined here Subjects_Codebook . Note, there will be one row for each subject in a published article. Measurements: Generate a .csv (comma-separated-value) file with columns that match the established WAI database table Measurements, defined here Measurements_Codebook. Note, there will one row for each frequency of each measurement. For example, if each WAI measurement has 100 frequencies, and there are 5 measurements, then there will be 500 rows.
What is WAI?
Wideband acoustic immittance (WAI) is an area of research that strives to develop WAI measurements as noninvasive auditory diagnostic tools for people of all ages. WAI measurements are reported in many related formats, including absorbance, admittance, impedance, power reflectance, and pressure reflectance. They can all be calculated from a single ear-canal pressure measurement and a measurement from the source’s Thevenin (or Norton) equivalent (WAI Mathematical Relationships).
