Re: children's hearing curve?

[Hiroko Terasawa <shiraiwa@xxxxxxxxxxxx>]

It is quite illuminating for me, because I didn't think about the  
hearing curve in terms of OAE by far - it is not a direct measurement  
of the hearing response but surely an evidence for the changing  
resonance over ages. Thanks a lot!
