In the Islamic Republic of Iran, certain heritage protection rules extend beyond physical preservation to include soundscape control around historic sites. For instance, in areas surrounding the ancient ruins of Persepolis and traditional gardens like Eram Garden, local lore and some municipal regulations discourage loud noises such as car horns, loud music, or even animated street celebrations. This unusual emphasis on quiet aims to preserve an atmosphere believed to reflect reverence for cultural history and allow visitors an immersive experience. While it may seem surprising, these noise restrictions trace back to longstanding customs valuing respect for places deemed sacred or historically significant. Some local stories even claim that excessive noise could 'disturb the spirits' of ancestors, although official documentation mainly highlights protecting the sensory environment. Verification of these rules varies between confirmed municipal ordinances and local-lore accounts, making it a fascinating example of how noise regulations intertwine with cultural heritage protection in Iran.
