The history of Suzhou Pingjiang Experimental School can be traced back to the first year of the Xianchun era in the Southern Song Dynasty (1265). It was relocated to its current site in front of the new school during the 20th year of the Jiajing era in the Ming Dynasty (1541). The scale of the school was second only to the Suzhou Fu School. The purpose of its instructional observation room is to provide students with a more intuitive understanding of the teaching content and the ability to ask questions at any time.

The instructional observation room at Suzhou Pingjiang Experimental Primary School covers an area of 296 square meters and can accommodate nearly a hundred students simultaneously. The traditional classroom model did not yield satisfactory teaching results, with teachers' voices often unclear to students, and student questions going unheard. Both teachers and students frequently complained about communication issues.

After completion, the instructional observation room utilized three Sennheiser TeamConnect Ceiling 2 ceiling array microphones and the ControlMax VoiceLift local sound amplification solution. This allows seamless communication between teachers and students, eliminating the need to shout, and ensuring that even lower volumes can be clearly heard by the other party.

Control Max VoiceLift is a revolutionary universal sound amplification solution that utilizes ceiling matrix microphones. It also features voice recording, automatic positioning with camera tracking, and a multi-room management platform.
