Phased array, used for large rooms. Well-designed phased array hearing loops give good, quality sound, no matter where a person sits.
Perimeter hearing loop, commonly used in small meeting rooms. Please consult with a qualified installer who can evaluate whether a perimeter hearing loop in the room will meet IEC standards. A person should be able to sit anywhere.
