Depending on where you live, there might be high noise levels around your home. In some cases, it could even be from inside your own home due to appliances or pipes. For some, this could disrupt sleep or just make for a daily annoyance.
Depending on the material your house is built of, the situation could be worse. A wooden home, for example, will not block out sounds as well as one made of cement. Your insulation also makes a big difference in how much of the outside noise is blocked. If you live in an area with heavy traffic, it could be worth it to invest in additional insulation to block out the noise.
Your windows also play a role in keeping sound out. Replacing single pane windows with double pane will make a big difference.
When it comes to your pipes, if you are experiencing noise when they vibrate, you can locate the source of the noise and make sure that there is enough clearance around the pipes. You also want to make sure that they are firmly anchored.
Replacing older appliances with more modern ones will ensure less noise as well.
