buzzes

Buzzes are sounds or sensations characterized by a low, continuous vibrating noise. In common usage, a buzz can refer to the audible tone produced by machines or insects, a feeling of excitement, or temporary changes in sensory perception.

In nature, buzzing is produced by many insects during flight or when vibrating body parts. The honeybee and bumblebee generate a characteristic buzz by rapid wingbeats; some bees also produce a higher-frequency buzz during pollination, a process known as buzz pollination where vibrations on flowers release pollen.

In electronics and engineering, a buzz describes unwanted or intentional audible sound arising from electrical equipment. Transformers, speakers, and electric motors can produce a mains frequency hum (commonly 50 or 60 Hz) or harmonics caused by magnetic forces and mechanical coupling. Buzz can indicate loose components, insufficient grounding, or resonance; mitigation includes mechanical dampening, isolation, proper wiring, shielding, or changing operating conditions.

The concept also exists in social and cultural contexts: a "buzz" refers to excitement, interest, and word-of-mouth generated around a person, product, or event. When media or marketing aims to stimulate attention, it is described as creating a buzz.

In health contexts, a persistent buzzing sensation may be described as tinnitus, a perception of sound without an external source, which can originate from hearing loss, noise exposure, or other medical conditions.
