The average apartment that you might live in is likely going to have floors that are either made of wood or dry wall. This is not an indication that your living space is in any way low quality, but there is a pretty good chance that these materials do cause a lot of resonance which means that your neighbors would likely hear a lot of what you are doing at any point throughout your day.
Suffice it to say that thin walls are not the only thing that should dictate the activities that you take part in since it’s not just your next door neighbors that would be bothered by your noise.
The truth of the situation is that when you have neighbors that are living downstairs they are almost certainly going to hear you when you are using a treadmill. This is because of the fact that the slight rocking motion that occurs when you are running on a treadmill creates vibrations that travel across your floor and can travel down to your neighbor’s walls as well. If you want to be a more caring and compassionate sort of person, buying the best quiet treadmill for apartment can help you achieve that type of personality for the most part.
There is nothing worse than having neighbors that don’t really care all that much about how the things you do disrupt their day to day lives. You wouldn’t want to have a neighbor like that, so you should try to avoid becoming that neighbor as well. Your own neighbors would probably be really happy that you are being so cognizant of their needs and they will treat you with more respect accordingly.
