Problems solved by technology

Although the noise estimation method for products has high accuracy, the noise estimation method has the problem of consuming considerable cost and requiring a lot of time and effort
In particular, for mass production, it is impossible to test all products one by one, and it is difficult to estimate the noise from products using only sample testing
[0007] Furthermore, the noise estimation method according to the related art may distort the pure tone of the product when a noise-causing object such as a computer exists around the anechoic room
[0008] In particular, since the measurement distance between the product and the microphone is spaced apart from each other, the sound quality estimation may vary depending on conditions and circumstances, making it impossible to measure noise objectively

Abstract

Disclosed herein is a pure tone test apparatus including: a stage including a support supporting a pure tone test target; a support plate mounted on one side of the stage and having a guide mounted on a front surface thereof; an acoustic detection unit movably mounted on the guide and being engaged with the support to detect noise generated from the target; a control unit connected with the guide, the acoustic detection unit, and the support to control a pure tone test; and a display unit displaying a pure tone test result detected by the control of the control unit.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2012-0028273, filed March 20, 2012, entitled "Pure Tone Test Apparatus and Control Method Thereof," the entire contents of which are incorporated herein by reference. technical field [0003] The invention relates to a pure tone test device and a method for controlling the pure tone test device. Background technique [0004] Most electronic equipment or similar equipment may generate large and small driving noises due to the characteristics of their structure. In poor environments, driving noise from electronic equipment or the like can cause distress and stress to the user. Therefore, minimizing the driving noise of electronic equipment or the like is a basic problem to be solved in order to improve the quality of life of people. Recently, various devices have been developed or various methods have been tried to minimize noise. [0005] Meanwhi...
