Sirens are loud due to their design and purpose. They use high-decibel sound waves created by a rapidly spinning rotor inside the siren. This design amplifies the sound effectively, which is crucial for alerting people and gaining attention over long distances, even in noisy environments.
FAQs & Answers
- What decibel level do most sirens operate at? Most emergency vehicle sirens operate at levels that can exceed 120 decibels to ensure they can be heard over ambient noise.
- What materials are used to make sirens? Sirens are often made from durable materials like metal or high-quality plastics to withstand environmental factors.
- How do modern digital sirens differ from traditional ones? Modern digital sirens can produce a wider range of sounds and can be programmed for different alerts, improving response flexibility.
