Explanation

Sound waves diffract (bend) around corners, allowing us to hear them,

While light waves do not diffract as much, making it impossible to see around corners.

Diffraction is the bending of waves around obstacles or through openings.

Sound waves have longer wavelengths than light waves, which makes diffraction more noticeable for sound.

Polarization is a property of transverse waves, and while light waves can be polarized, sound waves cannot.

Dispersion is the separation of waves into different frequencies,

And while it can occur with light, it's not why we can hear around corners.
