What Causes Loud Low-Frequency Noise and Ear Pressure in the Car?
4 Answers
The vehicle engine is one source of car noise, and its mechanical noise varies with the engine speed (primarily transmitted into the cabin through: the front fender, hood, firewall, and exhaust pipe). Relevant information about car engines is as follows: 1. Introduction: A car engine is the device that provides power to the vehicle, acting as the heart of the car, determining its power, fuel efficiency, stability, and environmental performance. Common gasoline and diesel engines are both types of reciprocating piston internal combustion engines. 2. Classification: Based on the power source, car engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid types, among others.
I often encounter low-frequency buzzing noises inside the car while driving, which makes my ears feel uncomfortably pressurized. This might be related to the tires, such as uneven tire wear or insufficient air pressure, causing loud rotational sounds. Additionally, a loose or worn engine belt could transmit low-frequency resonance into the cabin, especially noticeable when turning on highways. It's effective to check the tire balance and get a dynamic balancing test at a repair shop. Poor window sealing might also let in noise, so inspecting the condition of the seals during regular car washes can prevent issues and ensure a comfortable and safe driving experience.
When there is excessive low-frequency noise in the car causing ear discomfort, I believe the main causes may be an exhaust system leak or resonance. Cracks in the exhaust pipes can amplify low-frequency sound waves; loose engine mounting brackets can also vibrate the cabin, creating a buzzing sensation. It is recommended to first check if the exhaust outlets are rusted or damaged, while also testing the suspension system—failed springs or shock absorbers can increase noise intensity. Conduct simple checks before driving to prevent the problem from worsening, and regular maintenance such as oil changes can keep components running smoothly and reduce annoying disturbances.
Low-frequency noise during driving causes ear discomfort. My first reaction is to check if the wheels are damaged or affected by the road surface, such as uneven tire wear patterns causing vibrations and noise. At higher speeds, the sound amplifies, possibly indicating issues with the fan or air conditioning system. Ensuring all windows are closed and tire pressure is normal can help alleviate the problem. For safety, don’t ignore it—seek professional repair as soon as possible.
