Fire siren regulations involve various stakeholders including fire departments, police, manufacturers, and distributors. These entities collaborate to ensure fire safety and compliance with national codes, local building codes, and NIST guidelines. Acoustical engineers and sound level meters contribute to appropriate noise levels and mitigation, while fire science institutions and fire safety institutes provide education and research support. Closely related agencies such as municipal governments, NFPA, and IAFF participate in policy development and advocacy.
