[4.1 Calculation of acoustic condition values]
The acoustic condition value calculation process executed by the acoustic condition value calculation unit 16 will be described.
When the acoustic condition value calculation unit 16 takes in the environmental conditions for the flooring material, the wall material, and the ceiling material supplied by the selection condition acquisition unit 151, the acoustic condition value calculation unit 16 uses the parameter values corresponding to the flooring material, the wall material, and the ceiling material, respectively. A certain sound absorption rate is read from the parameter storage unit 13. In addition, the acoustic condition value calculation unit 16 captures an environmental condition regarding the size of the room supplied by the selection condition acquisition unit 151. When the captured room size is the number of tatami mats, the acoustic condition value calculation unit 16 reads an area value that is a parameter value corresponding to the number of tatami mats from the parameter storage unit 13. Alternatively, the acoustic condition value calculation unit 16 converts the tatami mat number into an area value.

The acoustic condition value calculation unit 16 calculates the reverberation time of the room by, for example, the following equation (1), which is an evaluation function, based on the sound absorption coefficient and the room area value corresponding to the floor material, the wall material, and the ceiling material, respectively. Calculate T. However, K is a reverberation coefficient (0.16 at 20 degrees Celsius), V is the volume value of the room, S is flooring, wall coverings, and the total area value of the ceiling material, _{a n} is the sound absorption coefficient of the member, _{S n} is The area of the member. As specified value the height values of the room, the acoustic condition value calculating unit 16 calculates the volume value V based on the area value S _n of the height value and the member.

  In addition, when the acoustic condition value calculation unit 16 captures the listener conditions regarding the listening location, the number of listeners, and the required sound quality supplied by the selection condition acquisition unit 151, the acoustic condition value calculation unit 16 corresponds to each of the listening location, the number of listeners, and the required sound quality. The listening position information, the required area value, and the required sound quality information, which are parameter values, are read from the parameter storage unit 13.

Based on the listening position information, the required area value, and the required sound quality information, the acoustic condition value calculation unit 16 performs, for example, the required minimum number LA _min and the required maximum speaker by the following equation (2) that is an evaluation function: The number LA _max and the speaker installation angle SL are calculated. Here, m is the required area value of the listening area, q is the required sound quality information, SP is the speaker installation direction angle viewed from the listening position, and l (el) is the listening position information.

To do.
The acoustic condition value calculation unit 16 has a rectangular room shape, a room size of 12 tatami mats, flooring is flooring, wall material is gypsum board, and ceiling material is wood, so the reverberation time is 0 at 500 Hz. The acoustic condition value indicating about 8 seconds is calculated by the evaluation function.
In addition, the acoustic condition value calculation unit 16 cannot embed the speaker in the wall surface because the desired acoustic device is a discrete speaker, the building age is three years, and the building type is a condominium. An acoustic condition value indicating that it is necessary to install on the sound is calculated by an evaluation function.

In addition, since the acoustic condition value calculation unit 16 has a viewing place behind the room, the number of viewers is four, and the required sound quality is an emphasis on the overall envelopment feeling, the listening area where the envelopment feeling is held is, for example, It is necessary to secure the left and right 200cm, and the front and rear 50cm, acoustic condition that indicates that it is necessary to arrange 12 speakers, the speaker layout is reinforced at the back of the room in addition to the uniform layout The value is calculated by an evaluation function.

The maximum allowable sound pressure O (O), the acoustic equipment installation constraint value E, and the like are captured. Further, the evaluation value calculation unit 17 takes in installation plan designation information supplied by the installation plan designation unit 152. Then, evaluation value calculation unit 17, as shown in Equation (4) below, comprehensively evaluated in accordance with acoustics value taken to the installation plan, calculates the quantitative evaluation value SP _x. However, w ₁ , w ₂ , w ₃ , w ₄ , w ₅ , w _6, etc. are weighting factors determined according to the designation information of the installation plan.

That is, the evaluation value calculation unit 17, the weighting coefficients _{w 1} to the processing _g 1 (T) based on the reverberation time T, the process based on the required minimum number _{LA min} speaker _g 2 _{(LA min)} the weight factor _{w 2,} the speaker process based on the required maximum number of _{LA max g} 3 _{(LA max)} to the weighting coefficient _{w 3,} in the process _g 4 (SL) based on the installation angle SL speaker weighting factor _{w 4,} the reproduced sound maximum permissible sound pressure O (O) The evaluation value SP _x is calculated by multiplying the processing g ₅ (O (O)) based on the weighting coefficient w ₅ , the processing g ₆ (E) based on the acoustic equipment installation constraint value E by the weighting coefficient w _{6, and the} like.

For example, when the installation plan designation information indicates “space efficiency emphasis” in FIG. 9, the evaluation value calculation unit 17 assigns a large weight to the evaluation value SP _x by performing a process using an acoustic condition value related to space efficiency. calculate. Specifically, the evaluation value calculating unit 17 uses the weighting factor w ₂ of the process g ₂ (LA _min ) to which the required minimum number LA _min of speakers is applied to the process g ₃ (LA _max ) to which the required maximum number LA _max of speakers is applied. ) To be larger than the weighting factor w ₃ , and the evaluation value SP _x of the space efficiency-oriented plan is calculated.

When the installation plan designation information indicates “sound quality emphasis” in FIG. 9, the evaluation value calculation unit 17 weights the evaluation condition SP _x by applying a large weight to the sound condition value related to the sound quality and the realistic sensation. Calculate Specifically, the evaluation value calculation unit 17 applies the weighting factor w ₃ of the process g ₃ (LA _max ) to which the required maximum number LA _max of speakers is applied to the process g ₂ (LA _min ) to which the minimum number of speakers LA _min is applied. The evaluation value SP _x of the sound quality emphasis plan is calculated by making it larger than the weighting factor w ₂ .
Further, when the installation plan designation information indicates “cost-oriented” in FIG. 9, the evaluation value calculation unit 17 assigns a larger weight to the process using the acoustic condition value related to the cost of installing the audio device and the audio device. Then, the evaluation value SP _x is calculated.
In addition, when the installation plan designation information indicates “internal focus” in FIG. 9, the evaluation value calculation unit 17 performs greater weighting on the process that applies the acoustic condition value related to the interior such as the room where the audio equipment is installed. to calculate the evaluation value SP _x Te.
