| ARTICLES RELATED TO Physics of music | | | |  Physics of music: Encyclopedia II - Valve sound - Negative feedbackAudio valves typically have only modest gain, and are more linear than bipolar transistors in the area of interest. This makes it possible to design very simple valve circuits that rely on this inherent open-loop linearity and have little, or indeed no, negative feedback, and thus have very simple distortion spectra.
Transistor amplifiers could achieve very high gains, so engineers use negative feedback to limit the gain. The feedback path used only resistors, which are highly linear. This results in very good, repeatable linearity. T ...

| | | | | | | Physics of music: Encyclopedia II - Valve sound - Bandwidth A significant aspect of the valve sound is that early valve amplifiers often had only limited bandwidth, in part due to passive component technology available at the time, notably capacitor coupled stages and output transformers. Tube stages were usually capacitively coupled, reducing low frequency response. Tubes could not directly drive speakers, so output transformers were used which further reduce high and low frequency response.
It must be remembered that the source material available at this time (usually vinyl records) lacked t ...

| | | | | Physics of music: Encyclopedia II - Sound - Types of sounds Noises are irregular and disordered vibrations including all possible frequencies. Their wave diagram does not repeat in time. Noise is an aperiodic series of waves.
Sounds that are sine waves with fixed frequency and amplitude are perceived as pure tones. While sound waves are usually visualised as sine waves, sound waves can have arbitrary shapes and frequency content, limited only by the apparatus that generates them and the medium through which they travel. In fact, most sound waves consist of multiple overtones or h ...

| | | | | Physics of music: Encyclopedia II - Sound - Perception of sound The frequency range of sound audible to humans is approximately between 20 and 20,000 Hz. This range varies by individual and generally shrinks with age. It is also an uneven curve - sounds near 3,500 Hz are often perceived as louder than a sound with the same amplitude at a much lower or higher frequency. Above and below this range are ultrasound and infrasound, respectively. The amplitude range of sound for humans has a lower limit of 0dBSPL, called the threshold of hearing. Sound is technically at its upper limit at 194.09 dB. A ...
