Product Information on: Echo-Screen TDA model



Echo-ScreenÒ TDA

TEOAE, DPOAE & ABR in one hand


q       OAE and ABR in modular technology

q       automatically evaluation, short test time

q       auditory screening in two steps

q       one equipment – one probe

q       quick, easy, reliable, validated

     OAE & Automated ABR in one hand held screening device


TEOAE-screening: quick, easy, reliable, inexpensive, clinically validated


DPOAE-screening: quick, easy,  frequency specific information


Automatical ABR-measurement: The “gold-standard“ of audiology for screening with
the highest specificity


The modular combination increases  validity, saves time and money.


Clinically fully tested signal statistical algorithms for OAE and Automated ABR.


Approved OAE-technology combined with the unequalled performing specificity of an  ABR-screening test.
