In many people with tinnitus, the cause is not known. The ear is otherwise fine. What seems to happen is that signals are sent from the ear down the ear nerve to the hearing part of the brain. The brain interprets these signals as noise. It is not clear why these signals are sent from the ear.
Octane booster is  a product which is designed to rise the octane rating of the fuel. The main idea behind using boosters is to increase power and also vehicleâs efficiency in certain engines. These have anti knock additives which when added to fuel prevent the onset of knock (detonation or pre ignition).
Gasoline is primarily composed of octane. With that out of the way: the octane rating of gasoline only has a tangential relationship to the chemical octane. The octane rating is a measure of the resistance of gasoline and other fuels to detonation (engine knocking) in spark-ignition internal combustion engines.It is so named because a fuel composed of 100% iso-octane has an octane rating of 100.uels which are less resistant to detonation have an octane rating lower than 100, fuels that are more resistant to detonation have octane ratings greater than 100. Since ethanol is less explosive and more resistant to detonation than iso-octane, it has an octane rating greater than 100.
