Have you ever noticed how not every room sounds the same? In fact, the experience a listener has when listening to music or watching a movie is not always dependent on the quality of the sound system or the speaker arrangement. The acoustical treatment of the room as well as environmental factors can have a major impact on the crispness and quality of the sound.
One such factor that can impact sound dispersion is temperature. As the temperature fluctuates, it is often accompanied by humidity changes, both of which can affect the way sound travels and reflects throughout a room. So, should you consider the temperature of your environment and how hot and cold air is moving in your space? The sound design specialists at Acoustic Geometry discuss the impact of temperature on sound.
The Science of Sound and Temperature
The conventional wisdom that things move slower in cold temperatures (why car engines take longer to turn over, why your fingers slow down when outside in the winter, etc.) also holds true for sound. As the temperature in an environment rises, items moving within the air move faster. This pertains to both air molecules as well as sound waves. In fact, the speed of sound is not actually a constant value like the speed of light. If the temperature of a space were to decrease from room temperature to freezing, the speed of sound traveling in that space would decrease by about 13 meters per second. Thus, in warmer air, sound travels, and therefore reflects off of surfaces and around the room, at a faster rate.
One additional factor that could complicate this truth is the presence of humidity. If the air is very moist, the added density could actually slow down sound waves despite the increased temperature normally associated with humid air.
In short, the behavior of sound can change as the temperature and humidity profile changes.
Temperature and Humidity in Your Home: Impact of Temperature on Sound
What does this mean for the sound within your home? Put simply, if the conditions of your home remain relatively constant, your ear will likely not perceive any difference in the sound quality or character from one condition to the next. For example, whether you are attending a live outdoor concert on a hot day, or listening to music in a cool, dark room, as long as the experience is isolated, the conditions will likely not have much effect on how the sound hits your ears.
However, if the conditions are in flux, complications arise. In homes, this happens as the natural conditions outside conflict with the treated air inside, and there is not a tight seal to keep the two environments separated. For example, if your home is heated during a cold winter, and older windows let cold air seep into the house, you could run into problems as pockets of cold, dry air mix with warmer, more humidified air. This can create areas of the room with different sound intensities, reflections, and overall profile. If this takes place in a studio or practice room, it can be problematic.
Solutions to Drafty Windows
When it comes to keeping your home from constantly battling intrusive temperatures from drafty windows, you are faced with several options. You could always replace your windows entirely. However, this would entail a days-long project that renders the space unusable for a time, and most likely cost thousands of dollars. You could also outfit your windows with film treatments, but these fixes are messy and generally only last a single season.
Thankfully, there is another option – Climate Seal Acoustic Series window inserts. These custom-manufactured inserts fit within or over the window cavity and are virtually invisible once installed. Installation is so simple, you can do it yourself in just a few seconds. The airtight magnetic seal created by the inserts will prevent cool winter drafts from making you and your visitors uncomfortable, combat heating bills by increasing your home’s efficiency, and ensure the sound profile of your space is consistent.
If proper sound is important to you and your family, then treating your windows is a crucial step towards optimization of your space.
