About This Product

■Summary

・High quality two-way simultaneous communication method ・Development of non-magnetic sounding element device ・Development of high-quality audio driver amplifier...Frequency band 10Hz to 100KHz ・Auditory stimulus presentation driver amplifier... Adopts LR completely separated 2-driver system, crosstalk characteristic of 90 dB or more ・Developed headphones with non-magnetic sounding elements...It is recommended that MRI noise is 20 dB or more when used with earplugs. ・Developed a non-magnetic sounding element type inner ear tip phone...Ideal for 32Ch/64Ch narrow head coils (patent applied) ・Inner ear tip phone reduces MRI noise...outputs high-quality voice and music stimulation signals ・When MRI noise is 100dB, the inside of the inner ear tip phone is reduced to 75dB... MRI noise is reduced. ・The inner ear tip phone can also support hearing loss by using external auditory canal bone conduction and external auditory canal tympanic membrane conduction methods (patent registered) ・When MRI noise is 100dB, the inside of the inner ear tip phone is reduced to 75dB... MRI noise is reduced. ・The headphone microphone on the MRI side uses a newly developed patented high-sensitivity vertebral bone conduction optical microphone. ・Similarly, when using an inner ear tip phone, a vertebral bone conduction optical microphone is used to reduce MRI noise and output the subject's voice to the monitor speaker in the control room. - Headphones can be freely selected from two types: sounding element type and inner ear tip type using a switch. (See model number) ・Inputs include CD, AUX1, AUX2, and terminals, allowing you to select any input such as CD, PC, etc. You can listen to your own music by connecting a portable music player, smartphone, iPhone, etc. to the AUX1 terminal provided on the front panel. ・For fixed microphones, it is possible to automatically switch between audio and auditory signals using a PTT switch using a cable method. ・The monitor speaker in the control room allows you to hear the subject's voice with reduced MRI noise. ・This device does not have any noise effect on MRI images. ・Sounding element...Maximum sound pressure 90~120dB ・The ear tip method reduces MRI noise by around 3OdB...You can listen to voice/music with high quality sound.
