[The Preyer reflex in the normally-hearing guinea pig].
Our purpose is to find the minimum auditory level for the Preyer reflex in normally-hearing guinea pigs, examining a range of frequencies between 125 and 8,000 Hz. Therefore, a sound source is used which emits pure tone at different frequencies at the intensities which are required and in an open field at the necessary distance. The Preyer reflex turns up in a reliable and constant way in those frequencies between 500 and 6,000 Hz. The most frequent verified auditory level comes to 65-75 dB.
