Coulbourn Instruments' New Animal Acoustic Startle Response System is said to offer easier calibration and greater flexibility, facilitating researchers to generate more reliable and faster results.
The system features improved accuracy with a new, integrated design featuring built-in microphones within the acoustic chambers for SPL measurement.
It is no longer necessary to use an external SPL meter, making testing easier and removing ambient noise interference.
The system guarantees reliability and assurance that the specific stimulus is delivered to each chamber through four independent tone and white noise signal outputs.
With these multiple outputs, the impact of speaker variation between chambers is eliminated.
Greater flexibility can be achieved with the four independent signal sources, as the controller can run up to four different protocols simultaneously.
The system is said to be easier to use with Harvard's exclusive auto-stimulus calibration procedure - simply press a button and walk away; after a few minutes every audio stimulus in the protocol is calibrated.
