Frequently Asked Questions
Why is the sound of an ambulance siren different when it is moving toward you versus away?
This is the Doppler effect. When moving toward you, the ambulance compresses the sound waves, increasing frequency and making the pitch higher. When moving away, it stretches the waves, decreasing frequency and making the pitch lower.
How do ultrasonic pest repellents work?
These devices emit sound at frequencies above human hearing, typically above 20000 Hertz. Many pests are disturbed by these high-frequency sounds and avoid the area. However, effectiveness varies and is debated.
Why is sound louder in a small bathroom than in a large auditorium?
In a small bathroom, sound energy is concentrated in a small space, so it seems louder. In a large auditorium, the same energy spreads over a larger volume. Additionally, more reflections in the bathroom amplify the sound.
