Pink Noise Generator

Pink noise generator is invaluable for audio testing. This flat frequency noise response source quickly shows anomalies in room acoustics, speaker arrangements and networks. When you tune a TV to a non-existent station you will hear a sound and it is called white noise. Its frequency characteristics could be raised by 3dB with every increasing octave. For response testing this sound level is not suitable.

When 2dB or octave filter and the white noise source are combined it could achieve nearly matching sounds to pink noise. Most fundamental filter rolls get off at 6dB/octave and to achieve a 3dB/octave filer, multiple filter sections are used. Based on the flatness of the filter the number of sections is determined and having more filters has proved to be highly effective for this task.

A very good pink noise generator as well as a sound spectrum analyzer is the K4301 Pink Noise Generator SELF-Assembly electronic kit. The two aspects, pink noise generator and the spectrum analyzer are essential to analyze the acoustic properties of a living room. In addition, you need a microphone that has linear frequency characteristic nearly 20Hz to 20kHz. With an equalizer, you could check the sound as well as correct it. The said pink noise generator kit is adaptable easily to create white noise.

If you could bear technical specification like general statements it is useful to know the specific features with the K4301 Pink Noise Generator SELF-Assembly electronic kit. The equipment has 33 bit regulator sliding length, 30 to 100kHz adjustable clock frequency, 3db/octave (20Hz to 20kHz) pink noise filter, 150m Vrms output voltage, 1Kohm output impedance, 1-12VAC or 12 - 15VDC/5mA power fully and 72x43mm (2.8” x 1.7') PCB dimensions.

Pink noise generators are available as self-assembly electronic kit (KT) format as well. They are supplied in kit format and needed to be assembled. You normally receive packs of components, circuit board (PCB), instructions for assembling. However, you do not get detailed instruction. If you know the basics you would be able to assemble the components. In addition, you will have to get more items such as wires, fixing screws, soldering iron, wire cutters and some solders. If you need to make your own pink noise generator, you can easily get the details from the Internet. Nevertheless, to follow them you should have some knowledge in the highly complex noise generation fields. Some websites have diagrams to show its complicated structure in a more descriptive manner for any interested parties to follow.

This is not the type of generator that you would come across most of the times. It is only used for all these specific needs and could not suffice for alternative purposes which makes it not a flexible one at all.

Oil is mostly found in remote or offshore locations. The crude oil which is extracted has to be transported to refineries to make it into the different petroleum products which are used. Pipelines are the most inexpensive and safest methods of transferring oil from the excavating site or rig to...
