These exaggerations or gain if you will overwhelm surrounding frequencies and smother them to the point where they can not be heard at all. If one places a microphone within one of these modes, certain frequencies will not be heard at all and some frequencies will be too prominent in the recording. Bass boom is an example of a room modal issue that can smother and can exaggerate certain frequencies. Room modes can also smother higher frequencies above the room modal frequency.
A 30 cycle wave can blur and smear a 50 Hz. These lower frequency resonances are common in rooms and that is the reason that bass sounds bad in most rooms. Continue low-pressure build-up affects the attack and decay of each individual low-frequency note.
Low-frequency sound energy can be heard but one must allow for each notes appropriate attack and decay rates to be realized by reducing the sound pressure created by the build-up of the room contained energy. Wavelengths in our room need distance to travel freely and not be influenced by our room boundary surfaces such as our walls, ceilings, and floors.
In an ideal acoustical world, with full acoustic wavelength theory applied, all frequencies have the full wavelength distance to travel. Unfortunately, real estate is expensive and reality is much different. The half-wave theory allows for half the wavelength distance to travel freely and then bounce back towards the source and then fall short of the next boundary.
Half-wave theory must be the minimum governing consideration when we are seeking a flat room response at certain frequencies especially those below cycles in our home theater, listening, or recording studios.

Looking at the chart above, you'll notice a lot of overlap of fundamentals with drums, keyboards, guitar and male singers. This doesn't mean they all overlap all of the time—it just means they can potentially overlap. While the fundamental range of the bass extends up to around Hz, most bass playing occurs with fundamentals below that between 40Hz and Hz. Though many non-bass instruments can play in their lower range, they're not down there all of the time.
However, it can really depend on the style of music or the particular player. As a bassist, you need to be mindful of these other instruments. If you play high and they play low, you'll be crowding the same frequency range and the sound of the whole band will turn to mush. The more crowded a space gets, the more the instruments need to work together. Since the harmonics of the bass extend into everyone else's sonic territory, you need to be careful not to select a bass tone which fights with the other instruments.
We'll cover this more later in this series of articles. When you play bass with a drummer, the kick drum is very important. The kick drum is the big drum on the floor played with a foot pedal.
It's often called a bass drum. The bass and kick drum tend to play during most of a song, and they share a lot of the same frequency range—especially between Hz. Look at the chart again.

It is an important aspect of music with kick drum and concert bass drum. The speaker must react forcefully and quickly. The room also enters into the equation. We are investigating this area of reproduction. Stay tuned. More to come on this. Zero dB SPL is a defined arbitrary level. The lowest levels we can typically hear are in the dB SPL range. This level is very difficult and very expensive to produce in an audio system. To effectively extend response another octave to 20Hz at appropriately high levels requires subwoofers.
Our experience is that it is not possible to position the main speakers for maximum output in this octave, even if they can reproduce it, and at the same time position them for best overall musical performance above 40Hz. They would need to be quite close to the wall behind them to benefit from that reinforcement.
We all know that placement sounds very bad as the whole musical tonal structure is influenced negatively by reflection from that wall.
Stereo subwoofers are a must, not single subwoofers.
