Acoustic phone booths are small and enclosed spaces that are designed to provide a quiet and private environment for people to make phone calls. These booths are made of soundproof materials such as acoustic foam, insulation, and glass to prevent noise from seeping in or out. They often have ventilation systems to ensure comfortable temperatures and prevent stuffiness. Acoustic phone booths are typically equipped with features such as power and USB outlets, built-in lighting, and internal fans for air circulation. They can be used in various settings such as offices, airports, and public areas where private phone conversations are desired.
