Why Does Wood Make Noise?

If you have a home with wooden floors or a furniture made from wood, you probably have wondered why does wood make noise. There are many reasons, from Thermal expansion to Insect infiltration and mechanical stress. Let’s discuss a few of them. Wood sounds are often heard at night, when people are sleeping or otherwise secluded. The less noise you hear, the better your hearing will be. Having less noise in your home can also help you hear better.

Thermal expansion

Random house noises can be a symptom of thermal expansion, a process that causes structural members of a home to expand and contract. This movement occurs mostly lengthwise, causing strain to fasteners and joints. Wood planks have a grain that runs along their length, which is also the primary direction of expansion. This causes the wood to expand and contract at different rates, resulting in unsightly noises.

Previous studies show that wood can increase in volume based on its moisture content, and this expansion causes a variety of unpleasant noises. However, they were not able to determine how much of the wood is causing noise. The problem with this method is that the wood’s moisture content changes in temperature, and the measurement of this process requires special apparatus to maintain a constant moisture content. In addition, the specimens were kept on a precision balance before being measured for thermal expansion.

The same phenomenon applies to building materials. Wood contracts and expands according to the temperature and humidity. Building materials made of wood have joints where different materials meet, causing stress and cracking. Nails, for example, can lose their hold on the wood and break, causing a loud sound. Often, this is the cause of a creaky house. In addition to thermal expansion, the wood is also susceptible to shrinking and becoming uneven.

The coefficient of thermal expansion was measured in a chamber with a temperature and relative humidity controlled to maintain stable conditions. The measurements were performed using a monitran LVDT transducer with a stroke of one millimeter. The measurements were then averaged at 1 kHz to minimize noise. When a study is complete, a standardized test protocol can be used for further analysis. If a wood-framed home experiences excessive thermal expansion, it may be necessary to make some structural changes.

Insect infiltration

Insects make wood noise for a variety of reasons. Some are beneficial, like carpenter ants, while others may cause damage and cause a nuisance. However, it is important to recognize what causes this noise, and the steps you can take to prevent infestation. For example, if you see a pile of sawdust behind a wood stove, it’s probably the result of an infestation.

Termites make wood noise for several reasons. They make noise while moving around, chewing, and eating wood. The most obvious sound they make is called “head banging,” a fast-paced rattling sound. Soldier termites will also bang against the walls of their tunnels. Fortunately, the vast majority of termite infestations don’t reach the point of causing significant damage to a home.

Phorid flies are small black flies that feed on decaying organic matter. You can try drying any organic matter that might be in your home to eliminate them. You can also find these flies in the corners of your home, and you should always be sure to rinse your cans and bottles to make recycling easier. However, if you do see a fly, don’t worry! These flies aren’t harmful to humans.

Fungi are another major pest that make wood noise. Fungi provide important nutrients for humans, so they are a common food source for some wood-destroying insects. In addition to this, fungi make wood noisy in other ways, such as attracting termites and rodents. If the fungus infiltrates a home, they can destroy the entire structure, as well as the contents of the house.


Insects make noise, and wood is no exception. Many pests cause noise in their natural habitats. Some make unusual noises and are pleasant to listen to, while others are obnoxious. To hear a wide variety of insects in action, sit outside and listen. If you hear crickets or grasshoppers, you might wonder what causes these strange noises. If you’re unsure of the source of your pest’s noise, consider the following.

Termites: This noisy pest creates sounds by moving around the wood, eating, and chewing. A typical sound created by termites is “head banging,” a fast-paced, dry rattling sound. Soldier termites create a pounding sound by banging against the wood in their tunnels. These pests are a common nuisance. But if you suspect that termite activity is the cause of the noise, you can do something about it.

Deathwatch beetles: This species is known for its distinctive tapping sound when emerging from wood. Although deathwatch beetles are relatively rare, adults make this sound to attract the opposite sex. Other wood-boring beetles make ticking or scratching noises. You might also notice ticking or scratching sounds in wood, especially firewood. But, no matter what the cause, the main culprit behind these annoying noises is pests.

Common Furniture Beetle: This pest was originally from Europe, but it has spread throughout the world. The larvae of this insect feed on wood and then leave the wood in spring through a six to ten mm hole. The adult is distinctive by markings, and they prefer moist wood and plywood in old furniture. While they can damage wood, they do not cause any real harm to human life. In addition to termites, the insects can weaken the structural integrity of wooden furniture, so the first step is fumigating the home.

Mechanical stress

Acoustic properties of wood include acoustic resonance and sound absorption. Acoustic properties are directly related to density and modulus of elasticity. The ratio of these two properties determines the speed of sound in wood. Wood absorbs sound in varying degrees, depending on grain orientation and moisture content. Musical instruments are often made from selected spruce wood. The rate of sound absorption increases with age and temperature and decreases with amplitude and frequency.

Industrial development has provided the world with a comfortable life, but also exposed workers to the dangers of noise pollution. Woodworking operations often produce significant dust, noise and odours. These pollutants can damage hearing and affect the quality of life. The World Health Organization estimates that 250 million people are affected by noise pollution at work. Two thirds of those people live in developing countries. This problem has a wide range of causes, but it is generally related to the noise generated by wood machinery.

The type of timber used in planing can also cause wood to make noise. Dry timber is generally brittle and hard, and planing less than 20mm thick can greatly increase the noise level. As the width of the cut increases, the noise level above the blade also increases. Additionally, the use of dull knives or worm blades will increase the noise level. In addition to this, dull knives tend to cause wood to vibrate more than smooth ones, resulting in higher levels of noise.

Insect infestation

If you hear a thudding sound from your home, there are probably termites or other insects causing the noise. These insects are known to make their homes in wooden structures. If you can find a small insect with long translucent wings, this may be a sign of a termite infestation. They may live near plants or even in your home. They are not harmful, but their presence may indicate that your wood is infested.

Using a DAVIS program, we were able to identify insects by the pattern of impulses in a train of sound. Then we were able to use these impulses to discriminate between insects and background noise. We were able to distinguish the insect sounds from background noise by identifying bursts, which are comprised of six to 200 impulses. Bursts were found to be more common when larvae were present in the wood and fewer when they were not. These new findings may help us identify hidden pests.

Researchers have found that fungi that provide essential nutrients to humans may also cause a tree to make noise. They also provide the entire food supply of some types of wood-destroying insects. If you are experiencing a wood-making sound, it may be the result of an infestation. If you’re unsure about the cause of the noise, there are a variety of tests that can help you diagnose the problem.

If you hear these sounds, it’s most likely termites. Termites are notoriously noisy creatures and will make various noises while moving around the wood. Their loudest sound is known as head-banging, and it’s made by the soldiers of the colony, which bang against the walls of the tunnel. You can use these techniques to locate a termite colony. If you suspect the wood is infested, you should immediately seek treatment.
