Info about Acoustics
Acoustics in enclosed spaces
Acoustics is a type of science that deals with the production, effects, and the control of sound. It also involves a wide variety of other topics such as musical instruments, noise control, ultrasounds for medical examinations, sonar dealing with submarine detection and navigation, and seismology. Acoustics deals with the sound and vibrations that objects give off such as the sound and echoing vibrations from a rock concert. Acoustics deal with the characteristics and complexity of sound such as frequency, waves that sound can create also known as sound waves, amplitude, and the reaction of sound when it interacts with different types of environment.
Acoustics can also be more commonly known as sound quality. For example, if you were in a concert hall and an orchestra was playing; chances are the sound quality will be ten times brilliant because of the architectural layout design of the concert hall. This is why music is greatly related to music. Whatever the material of the concert hall, walls, or floors are made out of; the sound can enter a new medium and be either absorbed, reflected or transmitted. The type of material that sound is produced in, depending on the building and its structure will affect the quality of the sound. Acoustics is all about the science of sound and its effects. Different forms of acoustics that deal with the different aspects of sound and hearing include bioacoustics, physical acoustics, ultra-sonics, and architectural acoustics. In order for sound to travel, they require a medium which is a solid, liquid, or gas. Important factors to take into consideration when dealing and experimenting with sound, is the reverberation also known as reverb and interference. Interference is the combination of two types of systems of waves. These waves will reinforce, neutralize, or interfere with each other. It is most observed in electromagnetic and sound waves. Interference is when their are two sounds that can happen at the same exact time. When the condensations of the two sound waves collide, including their rarefactions, the waves will support and reinforce each other. Once reinforced, the sound will be much louder and stronger.
In an enclosed space, reverberation will be constant in sound and only caused by repetitive reflections. This reflection of sound causes an echo to happen. Depending on the frequency of the sound, and where the listener is standing to hear the sound, different levels of interference between the original sound and reflections of the sound will be produced. Reflections can be decreased or increased by the interior or exterior of material used. Most recording studios are made to be absorbent to drown out all extra noise to not interfere with the music being created. Other sound absorbent materials can have a soft texture and are carpets, plaster, draperies, and upholstery. When in a crowded room, acoustics are also affected by the number of people in a room and also the weight of a person. The more people in a room, the less reverb (echo) or sound will be reflected to hear. The less people in a room, their will be much higher acoustics.
