H_i-Fi归根结底是为欣赏音乐服务的,而好的音响效果会加深音乐的感染力及对音乐的理解。音响器材技术指标中,常见TIM失真(瞬态互调失真),这是当今音响界极为重视的一项指标。其具体的听音表现是:乍听似乎高音清脆悦耳;然而久听就会觉得噪耳,令人疲乏;仔细分辨,又会感觉到这种音响效果既干涩又模糊,缺少透明度,乐器的音色无余韵可言;声像定位不准确,播放人声节目会发现舌齿分离现象,甚至听到不应有的二重音。其实,许多性能低劣的音响器材常会产生这种不良效果。
H_i-Fi in the final analysis is to enjoy the music service, and good sound effects will deepen the appeal of music and music understanding. Audio equipment technical indicators, the common TIM distortion (transient intermodulation distortion), which is today’s audio industry attaches great importance to an indicator. Its specific listening performance is: at first glance seems crisp and melodious melodious; however, long time listening will feel noise, tired; carefully distinguish, but also feel this sound is both dry and fuzzy, the lack of transparency, the tone of the instrument No afloat at all; audio and video positioning is not accurate, the program will find the separation of human voice teeth separation phenomenon, and even heard should not have the double tone. In fact, many of the poor performance of audio equipment often produce such adverse effects.
