Japan has a long history of providing solutions for sound and vibration, diagnostics, and anomaly detection that are tailored to the actual needs of our clients.
We continue to take on new challenges with the belief that we must always deliver value that exceeds the expectations of our clients and users, without being bound by industry norms and without fear of failure.

Aiming to make further progress together with our clients, we would like to introduce a total solution developed with the hope of supporting everyone, anytime, anywhere, with our motto.
This software, with human sensitivity at its core, leads to problem solving through intuitive operation.
Our wish is to deliver the moment of problem solving not only as a result shown by a machine or device, but also as an emotion that “makes sense” to the senses.

Practice is better than learning with psychoacoustic analysis as the theme – the structure emphasizes practice rather than theory.
Delivery includes examples of analysis of each psychoacoustic index (gas engine, machine sound, piston rattle, PC-HDD); Articulation Index (AI) and speech intelligibility are not covered.
Recommended for field engineers, quality, management, development, and marketing departments.

About psychoacoustic analysis, psychoacoustics is a standard approach to sound quality, but it is generally considered to be complicated with many indices, and is often perceived as difficult for beginners.
One of the reasons for this is the abstract nature of the terminology.

Roughness, one of the psychoacoustic indices, is sometimes translated as “roughness,” but to be honest, we do not know what exactly it means when we are told that it is “roughness.
Sharpness is also considered to mean “sharpness,” but people perceive it in different ways.
It is not surprising that people feel uncomfortable with the method itself before quantifying and understanding it.

Furthermore, as is true in other academic fields, the use of imported and translated terminology sometimes hinders the understanding of concepts that are not originally so difficult to grasp.
The TV drama of the past, “Detective Columbo,” had an episode depicting a crime that used subliminal effects to influence the viewer’s subconscious by inserting a momentary cut in the image.

Although there is a view that the subliminal effect of images has little basis in modern science, sound certainly has the power to affect people’s unconscious, change their mood, and influence their impression of the product, just like the subliminal effect that Columbo used as a clue to solve the case.
Music and even seemingly inorganic sound signals can move people’s hearts and minds.

The characteristics of sound that appeal to the human psyche can be one of the factors that influence consumers’ willingness to purchase.
On the other hand, “people” are not averaged abstract beings, and each individual has his or her own “psychological” state.

It is difficult to capture “the sound that only I am interested in” or “the sound that only I like” with existing statistical methods, no matter how much resources are invested.
We provide a one-package solution that combines psychoacoustic knowledge and technologies that cover individuality.
This is a challenge to solve the problem by using human sensitivity as a starting point.
