Do you mean:

Liberman MC

Auditory-nerve response from cats raised in a low-noise

chamber

J Acoust Soc Amer 63, 442-455

? or:

degeneration in acquired sensorineural hearing loss

Hope this helps,

Hello Geoff, many thanks for your great effort, but I am afraid that they are not what I am looking for, I remembered that there is a plot in which ambient noise level is functioning of activities of Animal Facility's staff within 24 h, and its effect on mouse hearing.

OK, then I suggest that you look through the list of Liberman's other publications:

https://www.ncbi.nlm.nih.gov/pubmed?term=Liberman%20MC%5BAuthor%5D

I think this is what you are looking for:

Liberman, M. C., Liberman, L. D., & Maison, S. F. (2014). Efferent Feedback Slows Cochlear Aging. The Journal of Neuroscience, 34(13), 4599-4607. doi: 10.1523/JNEUROSCI.4923-13.2014

Hello Markus, that is what I want, thanks a lot ! Hao
