Introduction
介绍：
Recently I’ve come across some attempts by two people to reproduce the famous (among the Meier-knowledgeable Ufologists that is) Beamship Sound.
最近，我遇到了两个尝试复制…（在Meier学识渊博的不明飞行物专家圈子里）很著名的「Beamship Sound/光船声音」…的人。
One was using a guitar amplifier, a microphone and a tape recorder.
（其中）一个使用一台吉他扩音器，一只麦克风和一台录音机。
The other used a model of the WCUFO suspended on a tensed fishing line tied between two trees.
另一个则使用了一个「WCUFO」的模型，该模型经由…一根绑在两棵树之间的绷紧的渔线…悬吊着。
In this article I compare all 3 sounds via looking at their spectrograms which is one way to “see" a sound over time.
在这篇文章中，我通过查看它们的频谱图来比较这3种声音，该频谱图是一种伴随时间的推进‘see/查看’声音的方法。
A spectrogram is created by applying certain Math formulae called “Fourier transforms" to the digitized waveform.
通过应用某些被称为‘Fourier transforms/傅里叶变换’的数学公式，频谱图被制成了数字化的波形。
A spectrogram typically shows time along the x-axis, frequency (pitch) along the y-axis and the amplitude (loudness) is presented as a brightness in the plotted data.
频谱图通常沿X轴显示时间、沿Y轴显示频率（音高），而振幅（响度）则在标绘的数据中显示为亮度。
The brighter the colour the higher the amplitude.
颜色越亮，振幅越高。
If you were ok at basic Mathematics at school you’ll be able to understand a spectrogram.
如果你在学校的基础数学（学习）没问题，你就能看懂频谱图（所示的内容）。
Original Beamship Sound
源版的「Beamship Sound/光船声音」：
You can listen to the original Beamship Sound right here:
你可以在这里听到源版的「Beamship Sound/光船声音」：
Beamship Sound Spectrogram
「Beamship Sound/光船声音」频谱图：
I’ve seen a spectrogram of the Beamship Sound before; Badr on the FIGU forum created one; however it wasn’t a very clear graphic so I’ve reproduced it here using Adobe Soundbooth CS4:
我之前曾见到过一个「Beamship Sound/光船声音」的频谱图；Badr在FIGU论坛上创建了一个；然而，它并不是一个很清晰的图形，所以，我使用Adobe Soundbooth CS4在这里将其重现：
If you examine the spectrogram to the right, which is only a 3-minute mp3-format ( 44Khz ) sample of the 20-minute full sample available from FIGU, then you can see that there are some obvious conclusions to make of it:
如果你检查频谱图的右侧，这只是一个…从FIGU获取的20分钟完整样本中截取的…3分钟mp3格式（44Khz）的样本，从中你可以看到，有一些明显的结论可以得出：
1. There are multiple, simultaneous frequencies present at many time-points. For example at time-point 0:30 there are about 8 clear and distinct frequencies stacked above each other.
1. 在许多时间点上，（都）存在多个同时频率。例如：在时间点0:30上，大约就有8个清晰明显的频率彼此堆叠在一起。
2. The number of different frequencies changes frequently over time. For example, at time-point 0:30 there are 8 distinct frequencies but at 0:45 there are 4 or 5 then at 1:10 it drops to
2. 不同频率的数量，会伴随时间的推进而频繁地发生改变。例如：在时间点0:30上，有8个不同的频率，但在（时间点）0:45上，就有4或5个（频率）…然后在（时间点）1:10上，又下降到了3个（频率）。
3. The values of each of the frequencies are constantly increasing and decreasing with time. The curliness of the horizontal lines on the spectrogram show this.
3. 每一个频率的值，都伴随时间而发生经常性地增加和减少。频谱图上的水平线曲率…表明了这一点。
Now compare that to 2 recent efforts to duplicate the Beamship Sound below.
现在，将源版频谱图与如下两次于近期（尝试）复制「Beamship Sound/光船声音」的（声音）频谱图进行对比：
Beamship Sound Reproduction Attempts
「Beamship Sound/光船声音」的复制尝试：
4.1 Amplifier Feedback
4.1 扩音器反馈
4.1.1 Overview of guitar amplifier feedback
4.1.1 吉他扩音器反馈概述
Some anonymous guy who calls himself Uzzz allegedly made this amplifier feedback effect with a guitar amp, tape recorder and a microphone:
一些自称为‘Uzzz’的匿名人士，据称使用一个吉他放大器，录音机和一只麦克风…制作了该扩音器的反馈效果：
4.1.2 Spectrogram of guitar amplifier feedback
4.1.2 吉他扩音器反馈的频谱图
A basic analysis shows clear differences in this sound sample to that of the Beamship Sound sample:
一项基本分析显示：该声音样本（的频谱图）与「Beamship Sound/光船声音」样本的（频谱图）之间，存在明显的差异：
1. The number of different frequencies changes infrequently over time. It has 5 or 6 visible and different frequencies present at most time-points.
1. 不同频率的数量，伴随时间的推进并未发生经常性改变。在绝大多数时间点上，都只存在5或6个可见且不同的频率。
2. The values of each of the frequencies are not constantly increasing and decreasing in with time. The straightness of the horizontal lines on the spectrogram show this.
2. 每一个频率的值，并未伴随时间而发生经常性的增加和减少。频谱图上的水平线直率..表明了这一点。
In fairness the uploader of this amplifier feedback video to Youtube claimed that the variableness of the frequency values could be reproduced with a pitch shifter but I haven’t seen this claim being tested yet and I do not have the required equipment so it’s not possible for me to verify that theory.
为公平起见，将这段扩音器反馈视频上传到Youtube的人声称：频率值的变量可以借助一个音高转换器再现，但是，对我来说，我尚未看到这种说法得到验证，与此同时，我也没有相应的（测试）设备，所以，我无法证实这个理论。
4.2 Fishing line vibrations
4.2 渔线振动
4.2.1 Overview of fishing line vibration effect
4.2.1 渔线振动效果概述
A British man called Phil Langdon has attempted to duplicate the Beamship Sounds using a small model of a Wedding Cake UFO suspended on a fishing line that was tied between two trees.
一位名叫Phil Langdon的英国男人，试图用一个悬吊在…一根绑在两棵树之间的…渔线上的「Wedding Cake UFO/‘婚礼蛋糕’型不明飞行物」（的）模型，来复制「Beamship Sounds/光船声音」。
The vibrations of the wind against the hollow model caused a similar effect to the Beamship Sound we are familiar with but it was far too quiet (like the amplifier feedback) compared to the 3km audibility of the original sound effect.
风吹动该空心模型所引起的振动，产生了一种与我们所熟悉的「Beamship Sound/光船声音」相类似的效果，但这与源版声音长达3km的可听度相比，实在是太安静了（如同扩音器反馈一样）。
The 3km loudness of the sound was according to multiple witnesses who also never saw any equipment apart from 4 tape recorders and an audio suppression unit that Meier held in order to prevent distortions of the recorded sound because of the excessive decibels coming from the beamship 60 metres above his head.
长达3公里的响度是基于多名（现场）目击者的描述，这些目击者同样没有看到任何其它设备，除了4台录音机和一台音频抑制器，后者（即：音频抑制器）是Meier用来防止录制的声音失真的，因为（在当时），过量的（声音）分贝从他头顶上方60米处的「Beamship/光船」传来。
4.2.2 Spectrogram of fishing line vibration effect
4.2.2 渔线振动效果频谱图
A basic analysis again shows clear differences in this sound sample to that of the Beamship Sound sample:
一项基本分析再次显示：该声音样本（的频谱图）与「Beamship Sound/光船声音」样本的（频谱图）之间，存在明显的差异：
1. The average number of different simultaneous frequencies present at any single point-in-time is 1. Not 4 or 5 or even 8, but just 1.
1. 出现在任何一个单一时间点上的…不同（的）同时频率的平均值，是1。不是4或5…又或甚至8，而只是1。
2. The rate of change of the single visible frequency’s value is small. The frequency of the sound changes over time but it does not change frequently.
2. 单一可见频率值的变化率，是很小的。声音的频率伴随时间的推进而发生变化，但不会发生经常性的变化。
Final Conclusion
最终结论：
So far the Beamship Sounds have still not been duplicated by any Earthly means.
到目前为止，「Beamship Sounds/光船声音」仍未被任何「Earth/地球」上的手段所（成功）复制。
There are similarities that are detectable by ear however when viewing the sound reproductions in the form of a spectrogram the differences become obvious and significant.
有一些被人类耳朵发觉到的相似之处，然而，当以频谱图的形式观察这些声音复制品时，其中的差异就变得显而易见且值得注意了。
The possibility that the original beamship sound originated from an actual and real beamship cannot be ruled out by any logical deduction.
源版「Beamship Sound/光船声音」是源自一艘实际且真实的「Beamship/光船」的可能性，不能通过任何逻辑演绎而被排除在外。
If it were easy to reproduce then why hasn’t it yet been done?
如果它（本来）很容易复制的话，那为什么至今都还没有完成呢？
Perhaps the logical answer is that it is a sound sample produced by an advanced technology, hence a beamship.
也许，合乎逻辑的答案是：它就是一种由某个先进科技所产生的声音样本，也就是说，是由一艘「Beamship/光船」产生的。
