A rossz akusztika következtében a diákok nem hallják a tanáraik mondanivalójának 50%-át, illetve a kórházi betegek alvási zavarokkal küzdenek és állandó stressz alatt állnak. 
Julian Treasure felhívja a tervezők figyelmét a hangzástervezés, azaz a "láthatatlan építészet" fontosságára. 

Julian Treasure: Miért fontos az, hogy az építészek a fülüket is használják a  tervezéshez?

Most buildings are designed for the eye, not the ear, leading to noisy hospitals and classrooms where recovery and learning suffer. In one study, students in a typical classroom missed half of what their teacher said because of poor acoustics. Constant noise also increases stress, causes more mistakes in healthcare, and even raises the risk of heart attacks for teachers. Attending to the invisible architecture of sound could transform well-being, behavior, and productivity everywhere we live, heal, and learn.

Ignoring Sound Sabotages Health, Learning, And Our Daily Lives

Ignoring the way spaces sound can harm well-being, hinder learning, and disrupt social connection. In many classrooms, students miss half of what teachers say because of poor acoustics, while hospital patients struggle to recover amid constant noise. Designing environments for the ears, not just the eyes, unlocks better communication, health, and focus. Simple changes like adding sound-absorbing materials can dramatically improve outcomes for everyone.
