【摘要】：自20世纪初第一台留声机诞生以来,声音的记录技术在源源不断的科技发展洪流中开始逐渐崭露头角。尤其是21世纪以来,随着数字科技的发展,音乐录音与混音技术更加凸显出其在音乐产业领域中的重要地位。由于声音本身具有音高、响度、音色等物理特性,由其物理特性衍生出的一系列声学现象是录音与混音中尤其要注意的环节。如何利用好某些对得到更完美音质有利的声学现象,如何在音乐制作中避免某些声学现象来破坏音乐作品的完成度,都将是当今混音中要特别注意的环节。在诸多声学效应中,本文将以声音的掩蔽效应(Masking Effect)为重点研究对象。目前国内外对掩蔽效应的理论及应用研究多见于建筑声学及医学领域。尤其在我国,掩蔽效应在音乐领域的研究多见于作曲技术理论的配器理论中,而在音乐制作领域中尚且是以宏观描述的形式为多见。掩蔽效应在音乐录音混音中是一个十分常见的声学现象。尤其在音乐混音的过程中,不同声轨之间因为某些因素的相似或相近将会产生很严重的相互掩蔽。如果从事混音工作的工作者不能及时加以处理,对混音得到的整体音响效果将会产生很大的不利。本文将使用定性分析法、描述性研究法、观察法、实验法、实例分析法等研究方法,通过客观数据分析及主观听觉感受,从声音的频率与频谱分布、响度与等响曲线等声学理论入手,通过四组听觉实验探究出掩蔽效应产生的条件——与频率和响度有着直接关系,又与声像设置有着间接关系,进而从声像、响度及频率这几个因素入手,重点分析如何在音乐混音中减少声轨之间的掩蔽,其中以底鼓与贝斯为例进行了主要探讨。关于掩蔽效应的所有研究都是以如何得到具有平衡饱满音响效果的音乐作品为最终目的。
[Abstract]:Since the birth of the first phonograph in 20th century, the recording technology of sound has begun to emerge gradually in the continuous development of science and technology, especially since 21th century, with the development of digital technology. Music recording and mixing technology more highlights its important position in the field of music industry. Because the sound itself has the physical characteristics of pitch, loudness, tone color and so on. A series of acoustical phenomena derived from their physical properties are especially important in recording and mixing. How to make good use of some acoustical phenomena which are beneficial to the more perfect sound quality. How to avoid some acoustical phenomena in music production to destroy the degree of completion of music works will be a special link in the present mixing. In many acoustic effects. The masking effect of masking will be used in this article. At present, the theory and application of masking effect are mostly found in the field of architectural acoustics and medicine, especially in our country. The study of masking effect in the field of music is often found in the orchestration theory of composition technology. However, in the field of music production, it is more often in the form of macro description. Masking effect is a very common acoustic phenomenon in music recording mixing, especially in the process of music mixing. Because of the similarity or proximity of certain factors between different tracks, there will be very serious mutual masking. If the workers engaged in mixing work can not be dealt with in time. The overall sound effect of mixing will have a great disadvantage. This paper will use qualitative analysis, descriptive research, observation, experimental, case analysis and other research methods, through objective data analysis and subjective auditory perception, from the frequency and spectrum distribution of sound. Based on the acoustical theory of loudness and equiaural curve, four groups of auditory experiments were conducted to find out that the conditions of masking effect were directly related to frequency and loudness, and indirectly related to the setting of sound and image. The loudness and frequency of these factors start with the emphasis on how to reduce the masking between tracks in music mixing. Taking the bottom drum and bass as an example, the main purpose of all the studies on masking effect is how to get a musical work with balanced and full sound effect as the ultimate goal.
