Abstract For our experiment we tested if music could blowout a lit candle. After doing research we think it is possible to blow a lit candle out using only music. The subwoofers would blow the candle out from pumping air in and out while music is playing causing the candle to go out. First we chose a selective variety of genres. After that we then played a song from each genre at half volume and max volume. The song with the most bass was played last and the song with least amount of bass was first. The different types of genres affected the bass from the subwoofer. The louder the music was the harder the bass of the subwoofer was and the higher chance of the candle going out.

Sound waves exist as variations of pressure in a medium such as air. They are created by the vibration of an object, which causes the air surrounding it to vibrate. The vibrating air then causes the human eardrum to vibrate, which the brain interprets as sound. Sound waves travel through air in much the same way as water waves travel through water. In fact, since water waves are easy to see and understand, they are often used as an analogy to illustrate how sound waves behave.
Sound is a phrase that typically refers to frequencies that the human ear can hear twenty Hz to twenty thousand Hz Sound is created by the fluctuation of air pressure caused by the movement and or vibration of a given object. When an object moves or vibrates, it transmits the kinetic energy to the air particles around it. The most common analogy for this is to visualize waves in water. Frequency is the word we use to describe the length of a single wave. The frequency is affected by the speed of vibration of the sound-creating object. Slower vibrations equate to lower-frequency sounds. Faster vibrations make higher-frequency sounds. When a sound's frequency is on the lower end of our hearing scale down near twenty Hz, we hear deep/low notes/sounds we commonly call Bass. When the frequency is up near twenty Hz, we hear high-pitched sounds we commonly call treble. We call the middle ground frequencies Midrange. Those of us who are fortunate enough to be able to hear most of these frequencies know that we are surrounded by sounds at all times, the world is a noisy place.
In order to hear, vibrations from the eardrum are interpreted by the brain that creates an understanding of the sound around us. Changes in the air pressure that glow into the ear is how sound travels from once source to the eardrum. Speakers produce changes in air pressure and that is how we hear our favorite television shows, movies or music through them.
In the past half a century, the subwoofer has completely changed the way people listen to and play music. Without them, low bass sounds would not be as clear and audible as they are today. If people recorded music or sound with a heavy bass, the entire sound would be muddled and not work correctly. The subwoofer, however, created clear, distinct bass sounds that can be altered by whoever is working the system the subwoofer is a part of. Listening to music anywhere has never been the same. Subwoofers, amplifiers and different types of speakers combine sound effects to reproduce them in a way our brains can interpret them for us. Once our brain does that, we are able to immerse ourselves in a world of make believe on TV or through music.
When designed and used appropriately, subwoofers can be extremely effective and very convenient. Equally, though, it is very easy to destroy any chance of good monitoring quality with an inappropriate or badly set-up subwoofer. Poor subwoofer installations usually suffer from too much, or poorly defined, bass. Often there is an obvious 'hole' in the frequency spectrum in the crossover region…
