Should classrooms use assistive hearing systems that boost certain frequencies based on each student's recent hearing test and seating position?

In this way, most students would benefit from improved hearing of the teacher without having to wear a hearing aid.

In terms of technology, recent research has shown that two ultrasonic beams can be emitted to intersect at a specific location to produce audible sound.

Another possibility is to place small speakers in each desk to boost certain frequencies.
