zumbido

The buzz of the bees was constant in the garden.

I always hear a hum in my ears after the concert.

The constant buzzing of bees around the hive is a relaxing sound for me.

The mosquito buzzed around me, making it impossible to concentrate on the book.

The bumblebee buzzed near the flowers, searching for nectar to take back to its hive.

The hornet landed on the window, buzzing with its characteristic sound.
