Turbojet engines, like any turbine engine are always very noisy because of the way they work.
Turbine engines do not have an enclosed combustion chamber like other engines, rather they have a fairly open-ended system. As burning fuel creates heat and expansion, it is used to propel an impeller which thus generates thrust. This system is highly dependent on air being able to quickly and easily enter and exit the engine in very high volumes. It is not possible to reduce the engine noise without also constricting this airflow and thus reducing the power output.
It is possible to make quiet turbojet engines, but making them quieter also makes them heavier and less powerful as well as reducing fuel efficiency.
Turbojet engine and aircraft designers must walk a fine line between noise reduction and performance.
jet engines, turbojet engines, turbo-prop engines, four-stroke piston driven engines... Can you be more specific?
No, a jet engine is louder.
A turbojet is one of the very first types of jet engine. Turbojets are different than turbofans- jet engines that most modern aircraft use.
Turbojet, turbofan and turboprop. Also, turboshaft and ramjet.

yes very load
Most if not all fighter jets use turbojet engines as they are the most efficient. The either use just the turbojet engine or it is modified to have a afterburner which causes the flame that you sometimes see at the back of jet fighters. One famous example is the F-14A Tomcat which was used in the film Topgun.
Frank Whittle designed the turbojet engine that is the foundation of all modern jet aircraft today.
The Grumman F9F Panther has one Pratt & Whitney J42-P-6/P-8 turbojet
Ordinary jet engines are used on aircrafts. But some planes require turbojet engines. These planes fly at more than the speed of sound. There are other type of airplane types too.
