Abstract
The utility model discloses an acoustic board. A platy sheet is provided with a plurality of through sound-absorbing holes. In the utility model, the through sound-absorbing holes are arranged on the sheet, so that the return vibration of sound waves can be effectively reduced, the noise is adsorbed, and when vehicles pass through the acoustic board, the generated sound reverberation is low, and the noise is low.
Description
Technical field
The utility model relates to a kind of sound arrester, particularly a kind of abatvoix.
Background technology
Sheet material class commonly used out of doors is placed on the road surface as provisional laying or as cover plate, because the vehicle contact is often arranged on the road surface, vehicle is understood sonorific reverberating when passing through this class sheet material class building facilities, produce huge noise, personnel's operate as normal and life around the influence.
The utility model content
In order to overcome above-mentioned defective, the utility model provides a kind of abatvoix, and this abatvoix can effectively reduce sound wave Hui Zhen, absorbs noise.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of abatvoix, and described tabular sheet material is provided with some sound-absorption hole that run through, and sound-absorption hole can reduce sound wave Hui Zhen, absorbs noise.
As further improvement of the utility model, described sound-absorption hole is rectangular distribution.
The beneficial effects of the utility model are: the utility model can effectively reduce sound wave Hui Zhen by the sound-absorption hole run through is set on sheet material, absorb noise, makes vehicle through out-of-date, sonorificly reverberates for a short time, and noise is low.
Description of drawings
Fig. 1 is the utility model structural principle schematic diagram.
The specific embodiment
Embodiment: a kind of abatvoix, described tabular sheet material is provided with some sound-absorption hole that run through 1, and sound-absorption hole 1 can reduce sound wave Hui Zhen, absorbs noise.
Described sound-absorption hole 1 is rectangular distribution.
Claims (2)
1. abatvoix, it is characterized in that: described tabular sheet material is provided with some sound-absorption hole that run through (1).
2. abatvoix according to claim 1 is characterized in that: described sound-absorption hole (1) is rectangular distribution.
