It is very possible. My mouse has the same problem, yet i have failed to fix it. I read on the website below that it has a respiratory problem. There are many causes of this. Mine was caused by cedar chips. <a href="http://www.rmca.org/Resources/mousefaq.htm">
My 1990 Lumina 3.1 had the same problem and it was caused by the crank sensor.
that would be the wings, like all flying insects that make a buzzing sound.
Bees do not make a sound like traditional animal vocalizations. The sounds they produce mainly come from the beating of their wings and movements inside the hive. Honeybees communicate through a series of vibrations that are often too subtle for humans to hear.

A honey bee's wings beat 11400 times per minute (180 beats a second) causing their buzz sound. I think the answer should be: Quote: "The buzzing sound is heard when the bee makes the air vibrate in some way. It used to be thought that the movement of the wings caused the sound. However the bees can buzz even when the wings are at rest. So it is probably the vibration of the muscles in the thorax causing the thorax to vibrate that makes the buzzing sound." From the website: http://www.bumblebee.org/faq.htm The wings of the bee make up less then one percent of the buzzing sound. The noise almost entirely comes from the bee breathing through its fourteen spiracles across its abdomen. This applies to all other buzzing insects, blue bottles, hornets ect.
When teeth chatters due to extreme cold, the sound is caused by the rapid contraction and expansion of the jaw muscles. This involuntary movement creates a clicking or chattering noise as the teeth repeatedly collide.

Ear noise, also known as tinnitus, is the perception of noise or ringing in the ears with no external sound present. It can be a result of various factors such as exposure to loud noise, age-related hearing loss, or underlying health conditions. Treatment options may include sound therapy, relaxation techniques, or hearing aids.
The buzzing noise of a wasp -- and any other insect for that matter -- is caused by the movement of its wings as they beat a couple of hundred times a second.
