Hissing noise in house

I sure hope you can help me. I have a hissing noise in my house that I have been unable to find in 4 1/2 yrs

The problem is, this noise always starts in the small hours of the morning, say from 2am - 6am. I have been unable to find this noise therefore, I have not had a decent nights rest.
I have a very simple house, septic system is a grinder pump and of course a water meter with pex pipes throughout the house.

Please, I have tried everything and since I live alone, have noone to even spend the night to validate this sound.

There is nothing wrong with my ears. I have excellent hearing.
Please help me find this noise or recommend someone who can.

Thank you for your time and consideration.

To solve this you are going to need to start eliminating things. You say you hearing is good, well just make sure next time you hear the hissing put your fingers in your ears to make sure it goes away. If it doesn't then it is internal i.e you have tinitus.

Next start turning things off at the mains. Your hifi can't hiss if it has no power, so try turning it off at the mains by unplugging it. If it is not your HiFi then start turning other things in your house off. Till you stop it.

Have a phiips tv had it in storage for over a year turned it on an the screen working perfectly but there a hising noise coming from the back of it do no what it is... Its a big bk tv not flat screen box...

hissing noise will be from high voltage regulator, i would suggest to do following:

1. switch tv off
2. remove plug from the wall
3. using air blower (compressor attachment - not leaf one!) blow the dust, especially from high voltage box section
4. connect the tv and switch on

if tv still issue hissing noise - follow 1 and 2 then:
3. remove back cover
4. use air blower again...
5. re-install back cover
6. reconnect tv and switch on

if hissing noise persist - check for blown capacitors on high voltage, replace if necessary, they have nasty tendency to pop if they are too long in storage, especially if tehy were overheated or frozen.

hope this will help you solve the problem, do not forget to vote...

My srm 450v2 is making a low hissing sound have changed the lead and power chord but its still the same if you tap the mic the noise stops until you start speaking again and it still does it when no xlr...

you may have a bad ground somewhere within the wiring. If the hiss disappears when you use the mic, it is probably because you are temporarily providing a ground with the x channel of your xlr. either the bad ground is within the speaker, or it is within the house wiring. if you have any fluorescent lights nearby, or on a similar circuit, you will get a hum or hiss. Beyond that, I'm not sure what it could be except possibly a blown component within the speaker.

Water heater makes a constant hissing noise with power on or off?

You have a water leak under the house, but need to know if it's a gas heater or electric. check the Pop off valve on top of the tank it has a short handle and should go threw the floor pull up on the valve and let it sit back down, if it stops the high pressure pop off valve is leaking, you can buy it and replace it for 5 or 10 bucks, if that does not stop it look under the house. Also use a broom stick and put the round end at the wall and the other end near your ear and check the wall and floor for the noise the closer you get the louder the sound. Hope this helps. If you look under the house and see water you know you got a leak in the pipes or the tank itself.

2000 Jeep Grand CHerokee has a hissing noise down near the brake pedal. Brakes seem to work but pedal seems to be "softer". Any suggestions? Thanks

There are some solutions for this kind of problems:
1. change your brake fluid (BF). This need to done regularly every three yrs. , at hard condition's every two yrs.
2. check the caliper. It's possible that one of the two pistions inside the caliper don't work properly (mud or rust inside)
3. check if the brake bads can slip free over the anchor, if there are some rust on it, remove them and check the surface, if damaged, replace the part.
4. check the caliper slide pins. If the caliper can not slide, it will stay in contact with the brake disk, this will heat up the bad and disk and make a noise.
5. check your brake booster (vacuum test required). If you switch of the engine, listen if your hear some noises (air leak!).
If all that wont work, come back again.

If trim controls or gains are set near maximum, HISS is normal as electronics generates a thermal type noise.

If gains are set in normal operating area, the noise SHOULD be minimal.

Other sources of interference like nearby radio transmitters, welders, arc lights, etc. can create noise.

Start with ALL gains turned down and find which if any cause the noise to be unacceptable.

MAKE SURE all power to this and ALL the other connected equipment come from a single receptacle to avoid ground loops.

Hissing noise coming from the rear of the car. I

probabbly not the brakes, maybe the tires but u need to check that, if u hear that noise with the engine running it might be a burned out gasket on your exhaust line

2002 Mitsubishi Galant ''hissing noise''

I would first try to locate the source of the hissing. Try spraying some engine starting fluid around the hissing area and home in on the source. The engine revs will change as the starting fluid is drawn into the engine. Sounds though more like a vacuum as you have suggested.

Noise through car speakers when connected to amp

If the subs are making a humming or RPM sound check your ground on the amp , make sure its a good ground. Always run your power wire from battery by itself down one side of vehicle. Groun should be no longer than 2 feet. If that dont help you can buy a noise supresor that goes inbetween your head unit and amp through RCA's with a ground on it . Hope this helps.
