Audio stimulus presentation DSP-based bidirectional communication system
It is a system that functions as a sound stimulation device in an MRI environment and allows for bidirectional communication between the subject and the operator. By using the optional RealFriend, the operator can communicate with the subject within the scan room. With the 1/3 octave filter setting, it outputs sound with a volume difference of ±4dB between 200 and 4000Hz. Even with a sound card that does not have sufficient output signal levels, it can output at a gain of 10 times the source.
