Common Terms Related to Sound Systems
Sound systems are available for rental or lease from many sources. You could test out an extravagant stereo for your car, or you could get a PA system for your next event. Regardless of your audio needs, following are some basic terms relating to sound systems.
Acoustic Feedback – Acoustic feedback is the high-pitched noise emitted from sound systems when the microphone picks up noise from the speakers. Acoustic feedback can be decreased or eliminated by lowering the speakers’ volume or by moving them farther away from the microphone.
Ambient Noise Level – Ambient noise level is the amount of background sounds that a sound system has to contend with. For example, your car’s audio system must compete with the sounds created by the engine and outside sources.
Clipping – Clipping is when a sound system is distorting because it cannot handle the volume. This means that the amplifier’s circuit is not powerful enough to support the signal.
Ducking – This is an ability of sound systems where the volume of music is automatically lowered to allow for audibility of a voice.
Filter – A filter is a piece of equipment that eliminates undesirable noises or frequencies from a sound system.
Patch Cord – These are short cables that connect the different parts of sound systems. Even a small home surround sound system will have patch cords.
Reverberation – Reverberation is when sound rebounds around an area even after the source of the noise has ended. In especially large rooms or spaces, speakers should take the reverberation of the location into account while presenting.
Shield – Shields are metal cases that surround electronic devices. This prevents any interference with the equipment from outside sources, and it protects outside devices from being affected by the sound equipment.
Businesses that rent sound systems and audio equipment usually have a wide variety of options for their customers. This allows them to serve the needs of more customers. If they limited the types of equipment that they rent, then they would only be able to serve a limited type of client.
Most rental companies now have sound systems and audio equipment for large concert halls and theaters as well as smaller, more intimate rooms. They might use the same type of DJ equipment, such as headphones, mics, mixers, turn tables, and portable music players, but they hock the equipment up to speakers and sub woofers that are specifically designed for certain environments. Too little power could mean that people have a hard time hearing speakers and music in large halls. Too much power in a small room, however, can create deafening noise levels.
Many stores offer short term and long term rental agreements. A club might want to rent equipment for several weeks so that their DJs have the turn tables, controllers, mixers, and speakers that they need for their events. The stores might also choose to lease portable music players, surround sound speakers, receivers, and digital turn tables to their clients. This allows the club to keep the audio equipment for long periods of time without spending a lot of money on week to week renting. Renting is often expensive compared to lease agreements. The stores might even offer a rent to own option that makes the equipment more affordable for entertainment companies, music halls, and other facilities.
