The exhaust system is falling apart probably from rust, have it checked soon, you don't want fumes getting into the car.
Sounds are louder when they are closer, because the sound is closer to your ears.
Sounds are louder when they have greater intensity or amplitude, which is the magnitude of the sound wave. The more energy a sound wave has, the louder it will be. Additionally, the distance between the sound source and the listener can also affect how loud a sound appears.
No, louder sounds do not travel faster than quieter sounds. Sound travels at the same speed regardless of its volume.
To make sounds louder, you can increase the volume or amplitude of the sound waves. To make sounds softer, you can decrease the volume or amplitude of the sound waves. This can be done using a volume control or adjusting the distance between the sound source and the listener.
Problem sounds like your hydraulic lifters. Might be a bad one or it can be dirty or even scorched. dvk of nyc.
Sounds can be louder at night compared to during the day due to lower levels of ambient noise and less sound interference, allowing sounds to travel further and be perceived as louder.
A humming noise on a 1999 Park Avenue is caused by bad wheel bearings. When bearings are loose or worn they will create a loud humming noise that will get louder and louder as the car accelerates.
Sounds are louder when they have a greater intensity, which is determined by the amplitude of the sound waves. The energy transmitted by the sound waves also affects how loud a sound is perceived. Additionally, the distance between the sound source and the listener can impact the perceived loudness.
how much the stereocilia of the hair cells are bent
I've had 3 astro's the fuel pumps are just loud has nothing to do with burn out. high pitched whine sounds like it's coming from the back seat much louder in the cargo version.
When you accelerate. you are putting presure on the main engine barrens. if they are going bad. You will hear this knocking sound. I don't know how many miles you have on this engine. But that's what it sounds like. But that's not all that can make this sound. You will have to tell more about it and when it started. Did it just start all at once? or did it start and then get louder?
It sounds like the power steering pump to me. my guess would be that you have a bad or loose belt ( sliping ) or you have a pully that is gonna either come flying off or lock up completely....neither is good. also a tight belt can cause the whine if it is tight the whine could be coming from the pulley bearings (alternator etc)
