What is intermittent noise?
Intermittent noise refers to a fluctuating noise level that experiences rapid increases and decreases. It is commonly observed in situations where factors such as passing trains, cyclical operation of factory equipment, or aircraft flying overhead contribute to the noise. The measurement of intermittent noise relies on the use of a sound level meter, which is similar to how we measure continuous noise.
In terms of categorization, there are four distinct types of noise that can be identified.
How to measure continuous noise?
For an adequate representation of the noise level, it is sufficient to measure continuous noise for a few minutes using a sound level meter. If a more in-depth analysis of the noise is desired, a sound level meter with octave band analysis capability should be sought. Octave bands enable the breakdown of noise into its individual frequencies.
What are the different types of noise?
In the realm of noise, there are several types that have become quite familiar. One of them is continuous noise, which is characterized by its uninterrupted, constant production. An example of this can be found in heating and ventilation systems.
Another type is intermittent noise, which is characterized by alternating quiet and noisy periods. In this case, the noise levels rise and fall rapidly, creating a mix of different sound levels.

Does the noise only occur when you accelerate or decelerate?
If you are hearing a loud vibrating noise in your car, there are several potential reasons for this issue. One possibility is that the vibration or noise only occurs at certain speeds or changes in direct proportion to the vehicle speed, which could indicate a vehicle speed sensitivity. Another possibility is that the vibration or noise is only noticeable when the vehicle speed changes, such as when starting from a stop, passing, slowing down, or coasting, which could indicate an acceleration/deceleration sensitivity. Additionally, worn-out components could also be contributing to this noise, such as motor mounts, struts, a failed driveshaft, or transmission parts. Finally, if the clunking noise only occurs as you accelerate, it is likely an issue with the engine that should be addressed as soon as possible.

Does the noise get louder or softer as you increase or decrease the speed?
When an object surpasses the speed of sound, it generates a sonic boom due to the inability of air to swiftly move aside, resulting in the formation of a shock wave.
This shock wave produces highly audible sounds that propagate behind the object, causing a significantly loud noise to be heard.
If sound were to travel faster in air, it would alter the way waves combine, leading to variations in the loudness of different frequencies.
Considering that frequency corresponds to pitch in sound waves, this would result in the production of an unusual and distorted vocal sound.

Why does sound get louder if you move away from a source?
When sound waves travel, they gradually decrease in amplitude, making them weaker (unless something amplifies them). This is why sounds appear to be louder when we are closer to the source. Conversely, as we move farther away from the source, the sound waves become smaller and softer, causing the volume of the sound reaching our ears to decrease.
Sounds can vary in terms of their intensity and pitch.
How does frequency affect sound quality?
Sound vibrations become smaller as we distance ourselves from the source, resulting in a decrease in volume. The frequency of the vibration determines the pitch of the sound, whether it sounds high or low. Frequency refers to the regular rate at which an event occurs. Sounds can vary in terms of volume and pitch.
Has the noise started after any recent repairs or maintenance?
There is a possibility that the repairs were not carried out thoroughly, leading to the issue. In order to address the problem, it is recommended to return the vehicle to the repair shop for them to inspect the work done.
