The duration of exposure needed to cause lasting harm decreases as the noise level increases. Here are the maximum noise levels permissible in workplace settings without the use of hearing protection and the corresponding time limits as recommended by the CDC.
Where do vibrations pass through the ear?
In the inner ear, sound vibrations pass through fluid in a structure known as the cochlea.
The cochlea is home to thousands of tiny hairs that aid in the conversion of sound vibrations into electrical signals.
These electrical signals are then transmitted to the brain.
Is the throttle body functioning properly without any carbon buildup?
Carbon deposits on the throttle body can negatively impact engine performance and overall fuel economy. This is due to the throttle body's role in regulating the air-fuel mixture. When carbon deposits build up, the throttle body's ability to accurately add air to the fuel is compromised, resulting in an imbalance of the air-fuel ratio.
Furthermore, these carbon deposits can also cause an uneven surface on the walls of the throttle body. This can disrupt the atomization of the air-fuel mixture, further reducing engine efficiency and causing issues such as rough idle.
