6 simple tips for soundproofing your whole house and easily say goodbye to noise problems.

For families with many members, soundproofing interior doors is crucial. It helps block noise from neighbors and reduces noise interference between family members. When choosing doors, solid wood core doors are the first choice, as they are less prone to warping under normal household conditions. Next best are perforated plywood doors, which offer both sound insulation and heat retention. If your budget is limited, solid wood composite doors are also an option, but avoid those with honeycomb paper cores. Additionally, adding a soundproofing strip to the bottom of the door will further improve sound insulation.

Soundproofing walls should be done during the renovation process. Generally, soundproofing felt and wallpaper are effective and space-saving; they're sufficient for basic soundproofing. If you want to further improve soundproofing, and your apartment layout allows, you can build a cabinet between your apartment and your neighbor's wall. After storing clothes, the soundproofing effect will be excellent. If you're planning to create a music room or recording studio, which require extremely high soundproofing, then use a combination of vibration dampers, sound-absorbing materials, and soundproofing felt to ensure that sound can be heard indoors but not outdoors.

Soundproofing the floor should be done during the floor leveling process. Usually, sound-absorbing mats or sound-absorbing cotton are laid. A few millimeters thick mats are generally effective, while a few centimeters thick mats are more effective but will increase the floor height, reducing the ceiling height. The best approach depends on individual needs and the noise level of your neighbors. Both wood flooring and tiles are suitable flooring materials. If you had to choose, wood flooring might offer slightly better sound insulation, but the difference is minimal. After renovation, you can also lay carpets, which can reduce noise to some extent, but the effect is limited.

Ceiling soundproofing should be done during the carpentry ceiling installation. Soundproofing felt is the most common material, as it's inexpensive and doesn't significantly reduce ceiling height, making it a popular choice. If you feel the soundproofing isn't sufficient, you can use a "sandwich" method: one layer of soundproofing felt, one layer of egg-yolk cotton, and then another layer of soundproofing felt. This greatly improves soundproofing, but it also increases the thickness considerably. The methods mentioned earlier for wall soundproofing-using vibration dampers, sound-absorbing cotton, framing, soundproofing felt, and soundproofing boards-also apply to ceilings, but they take up more ceiling height and are generally only used in special cases.

Bathroom noise mainly comes from the drainage system. Wrapping the drain pipes with sound-absorbing material can significantly reduce flushing noise; be sure to secure the tape properly. If you feel the sound-absorbing material isn't effective enough, and space allows, you can build a wall with solid red bricks. This will greatly reduce the noise from your upstairs neighbor's drainage; while it won't completely eliminate the sound, the effect will be noticeable.

1. Choose a casement window, as it has fewer gaps than a sliding window, closes more tightly, and naturally provides better sound insulation.

1. Don't choose single-pane glass. Triple-pane laminated glass has the best sound insulation effect, followed by triple-pane insulated glass and double-pane insulated glass. Laminated glass is expensive, while triple-pane insulated glass offers the best value for money.

1. For window frames, thermally broken aluminum is fine; there's no need for PVC. Thermally broken aluminum provides both sound insulation and heat preservation.
