buzzing

Other forms: buzzingly

If something is buzzing, it's vibrating or making a whirring sound, like a buzzing bee or a buzzing toy airplane.

Things making the sound of an angry insect are literally buzzing, like a buzzing doorbell or telephone. You can also use this adjective for more of a murmuring or whispering noise: "The buzzing lobby was full of eager fans waiting for the band to arrive." Buzzing comes from the verb buzz, which first appeared in the 15th century, echoing the sound it describes.
