Why use headphones or good loudspeakers for some demonstrations?

---

Some of the audio demonstrations contain signals with energy at or below 100 Hz. Small loudspeakers (like those in a laptop) do not transmit energy in this frequency range. Headphones and (larger) loudspeakers are constructed to efficiently convert these low frequencies so that they become audible. On a laptop you might hear nothing (if it is a 100Hz sine tone) or only the higher frequency components of a complex sound (and you might miss the effect that we want to demonstrate).

We actually recommend headphones or good speakers for all audio demonstrations (not only for those on this site).
