Noise Pollution

your valvetrain most likely has ro much play in it take it to the shop have them adjust it its like fifty bucks

its amazing

Improper engine timing usually

Could also be leaking / damaged intake valve(s)

or on an older engine with a carburetor if the accelerator pump is bad it will spit back when throttled up quickly

yes its true!

I have a 02 Sedona and I think I'm getting the same noise. It happens when you are driving and it sounds kind of like one of those slide whistles. I think it only happens when the A/C is on so that leads me to believe it is a vent or something that automatically opens and closes. Or maybe it's a ghost.

i also have an 04 sedona, and i frequently get noise which seems to come from the a/c heater motor.

I had that problem also on my 2004 Sedona EX and had it repaired at dealer. They replaced the rear AC purge/evaporator. Thank god for the warranty! They told me the noise complaints are similar to a ghost, siren, or motorcyle accellerating noise.

Appropriate protection from loud noises includes the use of earplugs or earmuffs designed to reduce sound levels. These devices can help prevent hearing damage in environments with high noise exposure, such as construction sites or concerts. Additionally, implementing soundproofing measures in workspaces or living areas can further minimize noise impact. Regular breaks from loud environments can also help protect hearing health.

A noise permit allows you to extend the normals times that your city will allow loud noises. An average noise permit will grant you 2 extra hours, depending on the day, to exceed the noise limit that your city has established for that time period. Every city and county is different, check with your local police station to find out more information on your city laws or to apply for one.

It varies on the amount of vehicles that you'll need to provide with CNG. It also varies based on the suction pressure of the gas.

Depending on the number of dispensers they can cost anywhere from $400K to $2.5Million!

A hissing noise is a sharp, sibilant sound often produced by the release of air or gas under pressure. It can occur in various contexts, such as when a snake hisses as a warning, when steam escapes from a kettle, or when air leaks from a tire. The sound is typically characterized by a high frequency and can indicate a range of situations, from harmless to potentially dangerous. In some cases, it may also signal a malfunction in machinery or appliances.

that dosent make sence there are many kinds of pollution in the world like litering or for trowing trash in the waters

Of course soundproof foam will reduce the noise escaping from the room. If you cover the walls and ceiling there will be very little noise escape through the floor.

Mice are very social animals. Their noises are their way of talking. Normal conversation for them sounds like quiet chatter. They also have quiet squeaks to show pleasure, as when they are being groomed. They have mid-range squeaks when they are being territorial, slightly louder short squeaks when they have fearful anticipation, and louder/longer high pitched squeaks when they are angry or hurt (physically or emotionally).

THG tested the noise level of coolers by using a sound meter to measure decibel levels at various distances from the unit while it was operating under different load conditions. This methodology allowed for a comprehensive assessment of the cooler's performance in terms of acoustic output. Additionally, they likely compared the noise levels to industry standards or competitor models to provide context for their findings. The results were then reported to give consumers an idea of the cooler's efficiency and quietness.

as a former Toyota technician, i saw some of these "whistlers". Try changing the PCV valve with a new one from Toyota.

if that doesnt work (it probably wont) try removing the spars on the roof rack (if equipt). I see this from time to time and it will drive you crazy! also make sure the rear windows are completely shut.

TRASH The garbage not our FUTURE.

The best way to prevent cobwebs is to keep the area clean. Frequently sweeping, vacuuming and dusting the entire area will keep cobwebs from developing.

Yes, a minor can make a noise complaint. The local police department is where you file a complaint.

sound travels at a certain speed but jets go faster than sound waves

Noise can be divided into three sub categories; external, internal, and semantic. External noise can be considered factors outside of a person that distracts them during communication. Typically it is the sights, sounds, smells, textures, and environmental factors. Internal noise can be one's thoughts or feelings that interfere with communication. Or in many cases, daydreaming, feeling tried, and illness. Semantic noise: Reactions aroused unintentionally by symbols or words, causing the listener to abruptly focus on an unrelated topic. In many cases the main reason of this occurrence is a poorly developed speech, in terms which the presenter did not fully understand or most likely underestimated the intellectually or the feelings of the audience. Most common forms of this noise are discriminatory remarks, red flag words, and controversial symbols.

"Without noise" refers to a state of absence of sound or disturbance, often implying a peaceful or calm environment. In a broader context, it can also describe a situation devoid of distractions or distractions that hinder focus and clarity. In communication, it suggests conveying messages clearly and effectively, free from misunderstandings or extraneous information.

It is a cause of error in Delta Modulation. When the original signal is nearly constant the output will vary due to long step size and appears to be varying.

or

If the original signal has small variations the output wave will look like square wave and will be recovered as DC component.
