3. ▲▼Studies conducted in several of these redesigned offices found that workers exposed to this noise for extended periods reported higher stress levels and made more errors on concentration-heavy tasks.
4. ▲▼Conversations, phone calls, and keyboard clatter now bounce freely off hard floors and glass partitions, creating a constant low hum that many employees find difficult to work through.
