¿Qué es el sonido?: frecuencia y tono

The video tutorial explores the concept of sound and frequency, highlighting the differences in sounds produced by various animals like sea lions and birds. It explains frequency as the number of complete waves passing a point in a given time, measured in Hertz. The tutorial discusses how frequency affects pitch, using a piano as an example, and compares high and low frequencies. It also covers the range of frequencies humans can hear, from 20 to 20,000 Hertz, and notes that animals like dolphins and dogs can detect higher frequencies beyond human hearing capabilities.
