Why do bass notes require a greater movement of speaker cone than mid to high notes?

Wavelength is the distance between two adjacent corresponding points in a wave pattern, and it is inversely proportional to frequency. This means that the lower the frequency, the longer the wavelength.

The human ear perceives sound by converting the vibrations in the air into electrical signals that are then interpreted by the brain. The amount of movement of the speaker cone is proportional to the amplitude of the sound wave. In order to produce a sound that is perceived as loud, the speaker cone must move more for a low-frequency sound than for a high-frequency sound.

This is because the ear is less sensitive to low-frequency sounds than to high-frequency sounds. In order to compensate for this, the speaker cone must move more for a low-frequency sound in order to produce the same perceived loudness.

Additionally, the size of the speaker cone also plays a role in the amount of movement required to produce sound. A larger speaker cone will be able to move more air than a smaller speaker cone, and therefore will be able to produce a louder sound.

Here is a table that shows the relationship between wavelength, frequency, and speaker cone movement:

| Wavelength (m) | Frequency (Hz) | Speaker Cone Movement |

|---|---|---|

| 1 | 343 | 1 mm |

| 0.5 | 686 | 2 mm |

| 0.25 | 1372 | 4 mm |

| 0.125 | 2744 | 8 mm |

| 0.0625 | 5488 | 16 mm |

As you can see from the table, the wavelength of a sound wave decreases as the frequency increases. This means that the speaker cone must move more for a low-frequency sound than for a high-frequency sound in order to produce the same perceived loudness.
