O-Solution options

Optional software is available for various purposes.

Digital Filter: OS-0521

Find quickly the frequency band of the noise

You can quickly find the frequency band that causes noise or vibration by applying an IIR or FIR filter to the recorded data and listen to the sound. The filter applied time series data can be saved as another file.

FFT Analysis Function: OS-0522

Grasp the frequency components and resonance frequencies

The most basic function used to observe the magnitude and resonance phenomena of vibration and sound in detail with analyzing the time axis wave form for each frequency components. It enables to calculate the power spectrum, frequency response function, coherence function, and attenuation ratio etc.

Along with the FFT analysis, you can simultaneously perform the octave, tracking analysis in real time.
* For the simultaneous measurement, the Tracking analysis function (OS-0523) and Octave analysis function (OS-0524) are required.




Check amplitude values such as acceleration, displacement and velocity (Tripartite graph)

It enables to show the tripartite graph*1. Three amplitude values (acceleration (m/s2), velocity (m/s) and displacement (m)) at any arbitrary frequency can be read simultaneously in real time . It is useful for evaluating floor vibration where precision equipment is installed.

By displaying VC curves*2, allowable vibration reference or setting environment evaluation of vibration sensitive instruments, such as semiconductor manufacturing equipment, AFMs, electronic microscopes, and laser interferometers is able to be judged quickly.

*1 The tripartite graph enables you to read amplitude values of acceleration (m/s2) and displacement (m) which is based on velocity (m/s), on the frequency (Hz) axis.

*2 The VC curves (Vibration Criterion Curves) are proposed as a guidelines for allowable micro-vibrations when installing precision equipment such as semiconductor manufacturing equipment and electron microscopes. It is used in 1/3 octave bandwidth evaluation. The criteria is divided into 7 levels every 6 dB (VC-A, VC-B, VC-C, VC-D, VC-E, VC-F, VC-G ) and used as a guideline for applications such as optical microscopes or laser devices with long optical path.


Tracking Analysis Function: OS-0523

Understand the sound and vibration characteristics of rotating object

You can understand the sound and vibration generated by rotating objects such as motors and generators, and at what rotation speed each order component becomes large. Tracking analysis with constant ratio and constant width, and offset tracking are also available.

The tracking analysis and the FFT analysis can be performed simultaneously in real time.
* For the simultaneous measurement, the FFT analysis function (OS-0522).

Octave Analysis Function: OS-0524

Measures environmental noise and vibration

This function is similar to the characteristics of the human ear (logarithmic (Log) to frequency) . Often used to understand noise and vibration levels and for measurements in accordance with ISO and JIS standards.

In the multiple analyses, you can simultaneously perform the FFT analysis and Octave analysis.
In measurement mode (real time measurement), 1/1, 1/3, 1/6, 1/12, 1/16, and 1/24 octave analysis is available.


Sound Power Level Using Sound Pressure: OS-0541

Conforming to standards applied to various objects

While the A-weighted Sound Pressure Level changes depending on the distance from a sound source or a test environment, the Sound Power Level is the specific value of a sound source. The measurement method is determined by international standards, and is a global indicator used in environmental labels such as Eco Mark, the Blue Angel and noise regulations. With the O-Solution /DS-5000, you can easily measure according to standards and check the sound source and frequency peaks. Thus, it allows you to take effective noise countermeasures.

Information Technology Equipment Option: OS-0542

Conforming to standards for office equipment

The measurement of noise emitted by computers, printers, multifunction devices, etc. is specified in the standard ISO 7779. This standard is also applied in obtaining environmental labels. It calculates emission sound pressure level at defined operator or bystander position as well as sound power level and the prominent discrete tones.

Sound Quality Evaluation Function: OS-0525

Sound quality evaluation considering human hearing characteristics

The sounds generated from the equipment are mainly measured by evaluation based on general analysis such as sound pressure level, FFT analysis and 1/3 Octave analysis. However, since those analysis don’t take into consideration the human hearing characteristics enough, sounds with even the same analysis result may give different impression.
When a human listens to a sound, various sensations such as loudness, sharpness, and roughness occur.
This function enables to obtain sound quality evaluation indicators that take into consideration the human hearing characteristics and correspond to various sensations of sound.

Fluctuation Sound Analysis Function: OS-0526

Evaluate the temporally fluctuating sounds

Although the magnitude of sound is not so large, there are many “unpleasant sounds” in the world.
For example, “rattling” and “humming“ sounds generated from interior parts while driving a car, or abnormal sounds such as “buzzing“ sounds that can be heard in the rotation sound of a small motor, etc. Sounds with significant temporal fluctuations often feel unpleasant even if the magnitude of sound(level) is not so large. The Fluctuation Sound Analysis Function enables to extract only the components with large temporal fluctuations that are not affected by the level. As a result, it can quantify the characteristics of various temporal fluctuations that were difficult to detect with roughness or fluctuation strength. In addition, it is equipped with a function to compare the sound with fluctuation and the sound without fluctuation.

Time Frequency Analysis Function: OS-0527

Evaluate transient phenomena

This function can evaluate transient phenomena that were difficult to capture by FFT analysis and display clearly time change of the frequency components while maintaining its frequency resolution. It is equipped with STFT (Short Time Fourier Transform) and Wavelet transform.

Statistical Analysis Function: OS-0531
