The second part contains In Depth explanations and background information of various acoustic phenomena’s and is referred to on several occasions in the first chapter.

Below, please find a description of the most common monitor placements and appropriate compensation. Using material from the calibration CD together with the AIR placement compensation settings could help the interaction between the AIR monitor and acoustics the studio.

  • Page 30: Calibrating The Subwoofer

    CALIBRATING THE SUBWOOFER - Bass Management Bass management (sometimes called bass redirection) is a very important and useful tool - and it is in general an absolute necessity if you want to make a 5-channel set-up in a small room! There are several reasons for this. The bass management system is designed to subtract the bass contents of all main channels and reproduce this by the use of a sub woofer.
  • Page 31 CALIBRATING THE SUBWOOFER - LFE Gain Range: 0 to +14dB The LFE channel can be boosted up to 18dB using this parameter. Polarity Range: 0 or 180º If the Subwoofer is correctly placed, setting the Polarity parameter at 180º should result in a full Phase cancellation at the set Cross -over frequency.

  • Page 32: Acoustics

    ACOUSTICS Acoustics When we talk about making a room "sound right", we are probably dealing with room acoustics as a science acoustics has been around for about hundred years. Until then good acoustics happened by experiment, by experience, or simply by accident. Today we know a lot about the parameters that influence the "sound"...

  • Page 33: Sabines Formula

    ACOUSTICS Sabines formula Sabine is the father of modern acoustics. He found that reverberation time is described by a relationship between the room size and the amount of absorption in the room. Larger rooms - longer reverberation. More absorption - shorter reverberation.

  • Page 34: Absorbers

    ACOUSTICS Absorbers All materials in the room act acoustically even if they are not so-called acoustical materials. Basically we have three kinds of absorbers. Membrane absorbers This kind of absorber includes wooden floors, windows, doors, etc. This absorber provides absorption in the low end of the frequency range.

  • Page 35: Standing Waves

    BACKGROUND INFO - ACOUSTICS Standing Waves Standing waves exist in all kind of rooms. The shape of the room, the dimensions of the room, and the relationship between the dimensions of the room, are important parameters that will determine the frequencies around which the phenomenon exists as well as the distribution of these standing waves.

  • Page 36: Room Modes

    Air_US_rev_111.qxd 16-12-2004 14:17 Page 34 ACOUSTICS - BACKGROUND INFO Room modes These special frequencies are also called room modes. Standing waves between parallel walls are called axial modes. Other modes exist. For instance tangential and radial modes. (See the illustration). Normally the axial modes are the strongest.
  • Page 37 ACOUSTICS The standing waves are characterized by having a maximum sound pressure at the boundaries of the room. Depending on the frequency there are one or more dips across the room. In a box shaped room the frequencies can be calculated as follows: where frequency in Hz speed of sound (approx.
  • Page 38 ACOUSTICS In practice the placement close to boundaries will influence the frequency range below 125-150 Hz. - BACKGROUND INFO At low frequencies a monitor can be considered as to radiate the sound energy in all directions. This is also called a 4 π radiation. When placing the monitor close to a solid boundary - for instance a wall - the sound energy that should have been radiated in the...

  • Page 39: Comb Filtering

    ACOUSTICS Comb Filtering The filtering function that arises when a signal is added to itself after having been delayed in time is called a comb filter. The resulting frequency response resembles a comb, hence the name. Two 500 Hz sinusoidal tones added. The second tone is delayed 1 ms hence the sum is zero Two 1 kHz sinusoidal tones added.
  • Page 40 ACOUSTICS Two typical situations in which comb filters arise, either acoustically or electrically. In general: All digital signal processing takes time. This means in practice that comb filter effects can arise if you loop a signal via, for example, a compressor and combine this signal with the original. An example of a comb filter created by the combining of two signals with the same amplitude, but with a time delay between them of just 1 ms.

  • Page 41: Rear Wall Cancellation

    ACOUSTICS Rear wall cancellation When the monitor is set up at some distance in front of a wall, reflections from the wall may occur and influence the perceived frequency response. This could result in comb filtering if all frequencies produced by the monitor were radiated in all directions.

  • Page 42: The Subwoofer

    THE SUBWOOFER The Subwoofer A subwoofer is a monitor that reproduces low frequencies. The purpose is to take over from the main monitor(s) as frequencies approach the lower end of the frequency range. I.e. approximately below 120 Hz. When used in professional monitor systems it is commonly preferred to use subwoofers below approximately 80 Hz.

  • Page 43: The Lfe Channel

    THE SUBWOOFER & LFE CHANNEL Checking summing phase cancellation In a basic 2-channel set-up or 5-channel set-up (like the ITU-775) a sub-woofer is not specified and is not required. But making audio production to be played back on consumer equipment, one has to ensure that the mix will sound right in this situation.

  • Page 44: Delaying Monitors

    DELAYING MONITORS ITU 775 When using a 5.x set-up with monitors arranged on a circle line (as with ITU 775) the distance from the listener to each of the main monitors is the same. In case of limited space the three front monitors can be arranged on a straight line.

  • Page 45: How To Measure The Sound Pressure

    LINE-UP & CALIBRATION Calibration of 5.1 in an ITU-775 arrangement In a 5.1 system based on the ITU arrangement, all main channels have in principle the same conditions: there is one monitor per channel and each is placed the same distance from the listener. Internationally, there is however neither agreement on the level nor on the bandwidth for the noise signals that is used for acoustic calibration.
