Terminology

10 Room Acoustics

This is an area that requires both a little background to

understand and some time and experimentation to attain

the best performance from your system.

Your room is actually a component and an important part

of your system. This component is a large variable and can

dramatically add to or subtract from a great sonic experience.

All sound is composed of waves. Each frequency has its

own wave size, with the lower, or bass frequencies literally

encompassing from 10 feet to as much as 40 feet. Your

room participates in this wave experience like a swim-

ming pool with waves reflecting and becoming enhanced

depending on the size and shape of the room and the

types of surfaces in the room.

Remember that your audio system can actually generate

all of the information required to recreate a sonic event in

time, space, and tonal balance. Acoustically, the role of

an ideal room would be to neither delete nor contribute

to that information. However, nearly every room does to

some degree.

Standing Waves

Sound coming from a speaker bounces around in a room

until a pattern emerges—this is called a standing wave.

Typically, this is only a problem with frequencies below

100Hz. When this happens different parts of your room

experience either an excess or a lack of bass.

Some people believe that having a room without parallel

walls will eliminate this effect. The truth is that non-parallel

walls only generate different standing wave patterns than

those that occur in rectangular rooms.

Usually, you can excite most of the standing waves in a

room by putting the Dynamo 300 in a corner. Listening

position determines which standing waves you will expe-

rience. For instance, if you sit in a corner you will hear

most of the standing waves. This can be an overpowering

experience. Sitting next to a wall can also intensify the lev-

els of the standing waves that are experienced.

Resonant Surfaces and Objects

All of the surfaces and objects in your room are subject to

the frequencies generated by your system. Much like an

instrument, they will vibrate and "carry on" in syncopation

with the music, and may contribute in a negative way to the

sound. Ringing, boominess, and even brightness can occur

simply because surfaces and objects are "singing along"

with your speakers.

Resonant Cavities

Small alcoves or closet type areas in your room can be

chambers that create their own "standing waves" and can

drum their own "one note" sounds.
