TABLE 2- Meter Control Settings
表 2 - 儀表控制設定
3.3.1. Calibrate the sound level meter using the appropriate meter calibrator and set meter on FRONTAL mode.
用適當的校准器校准聲級計,并設定到FRONTAL模式.

3.3.2. All Toys Excluding Caps 除火帽以外的所有玩具
3.3.2.1. Position the meter microphone 9.8 ins. (250 mm) from the noise-producing mechanism and orient the toy to allow the microphone to receive the highest sound level reading.
將聲級計的接收頭放于距噪音發生裝置9.8ins.(250mm)遠的地方,并調整其方向以便接收到最高的聲級讀數.
NOTE: If the normal operating distance of the toy is less than 9.8 ins. (250 mm) from the child’s ear ,test the toy from normal operating distance.
注意:如果使用玩具時離開小孩耳朵的正常距離小於9.8ins.(250 mm),那麼按正常距離進行試驗.
3.3.2.2. Activate the toy in the most severe position:
在產生噪音最高的位置使玩具發聲.
.1 Continuous - For analog type meters (no averaging function), record the meter reading in dB every 2 seconds for the duration of the phrase or sound effect.
對于連續式噪音用模擬型儀表,(無平均讀數功能),每2秒鍾記錄一次發聲時的dB讀數.
.2 Impulse - Record the highest reading.
對于脈衝式聲音-記錄最高讀數.
3.3.2.3. Repeat section 3.3.2.2 five times for each phrase or sound effect.
對于每個發聲周期,重覆步驟3.3.2.2五次.
3.3.3. Toy Caps 火帽玩具
3.3.3.1. Place the firing device and SPL meter no closer than 39 ins. (1 m) from any wall, floor, ceiling or other large obstruction.
將點火裝置和SPL聲級計置于距牆壁,地面,天花板及其它大阻擋物不小於39 ins. (1 m)遠的地方.””””””
3.3.3.2. Locate the firing device and the microphone in the same horizontal plane with 9.8 ins. (250 mm) between them. Mounting the product and/or meter on a tripod is acceptable.
在同一平面內把點火裝置及接收頭置於相距9.8 ins. (250 mm). 產品和/或聲級計放在三腳架中也可.
3.3.3.3. Measure the peak sound pressure level at each of the six designated orientations with respect to the measuring microphone. The 0symbol 176 \f "Symbol" \s 11°} orientation corresponds to the muzzle of the pistol/firing device pointing at the microphone. 90symbol 176 \f "Symbol" \s 11°}, 180symbol 176 \f "Symbol" \s 11°}, and 270symbol 176 \f "Symbol" \s 11°} are measured in a clockwise direction when looking down on the pistol with its barrel horizontal. Reference Figure 1.
將接收頭對眷指定的六個方向測量各處的聲級峰值,0symbol 176 \f "Symbol" \s 11°}方向是指發令槍/點火裝置的噴嘴對著接收頭, 90symbol 176 \f "Symbol" \s 11°}, 180symbol 176 \f "Symbol" \s 11°},和270symbol176\f"Symbol"\s11°}是指自發令槍筒開始,由上而下按順時針方向測量.參照圖1 .

FIGURE 1 - Firing Device Orientations
圖 1 點火裝置方位圖
The 5th and 6th orientations (hammer and trigger) rotate the pistol/firing device about the axis of the barrel, when the device is at 90symbol 176 \f "Symbol" \s 11°} or 270symbol 176 \f "Symbol" \s 11°}, so the hammer and trigger are closest to and in the same horizontal plane with the microphone.
第五及第六個方向(撞針及扳機)是指發令槍/點火裝置之槍筒旋轉的方向,當裝置在90symbol 176 \f "Symbol" \s 11°}或270symbol 176\f"Symbol"\s11°}方向時,撞針及扳機與接收頭最近并在同一平面上.
3.3.4. Calculations 計算
Because the SPL scale is logarithmic and not linear, convert readings first to their power level ratios, the ratios averaged and that average converted back to a logarithmic reading. Calculate the average of the sound pressure level readings taken as follows:
由于SPL值是對數值,且非線性,所以要將所測得的讀數轉化成聲強值,將聲強值取平均值,然后將所得到的平均比值轉化回對數讀數,計算聲級平均值讀數可釆用以下方法.
3.3.4.1. Convert each dB reading to its power ratio by dividing by 20 and taking the anti-log of the result. For example:
轉化每一dB讀數成聲強值 時,將dB值除以20再取反對數,例如
Power ratio = Anti-log [dB/20]
聲強值= Anti-log [dB/20]
Hence, for a dB reading of 78 RMS(A)
因而, dB讀數為78 RMS(A)
Power ratio = 7943.282347
聲強值 = 7943.282347
3.3.4.2. Determine the average of all of the power ratios (APR).
將各自計算出的聲強值取平均值.
3.3.4.3. Convert the average power ratio value (APR) determined above to an average dB reading as follows:
將所得的聲強平均值轉化成平均dB讀數可用以下方法.
Average dB = 20 log APR
平均dB讀數= 20 log APR
Hence, for an APR of 9418.6745
因而, 聲強值為9418.6745
Average dB = 80
平均dB讀數=80
