An intense, low-frequency tone (about 30 Hz) modulates the sensitivity of the inner ear to high-frequency stimulation. This modulation is correlated with the displacement of the basilar membrane. The findings suggest that the modulation may also affect cochlear tuning. We have investigated modulation of cochlear tuning by low-frequency sound in the guinea(More)
In comparative threat analysis, threats imposed by different environmental problems are measured and compared. This type of analysis can be used to assess the overall threat to the environment, and to identify the most serious threat ('key problem') and areas which are particularly threatened ('problem areas').
