But it cannot be inferred whether it is related to the quality of the house, because:
First of all, from the perspective of architectural acoustics, it can be divided into air-borne noise and structure-borne noise. Generally speaking, the room near the window is mainly affected by outdoor noise (such as square dance music), while the room far away from the window (not adjacent to the noise source) is mainly affected by outdoor noise through the structure.
As for whether it has anything to do with the quality of the building, it is because you can feel the vibration and hear the noise (noise is also the vibration of the air. It must be remembered that the eardrum is more sensitive to vibration than the limbs, but the lower limit of the frequency that can be felt by hearing is about 20Hz, and the lower limit of the frequency that can be felt by the limbs is about 0Hz), which is influenced by many factors (such as incompleteness):
1) Intensity and frequency of vibration source
2) the distance and relative position between the vibration source and the building
3) Propagation medium (attenuation is different after passing through soil, gravel and rock)
4) the weight of the building (low-rise buildings with steel structure are easy to be excited, and medium-high-rise buildings with concrete structure are not easy to be excited)
5) Elasticity of building floor (due to its structural design, the vertical amplitude of the floor can be as high as 1cm in the case of structural safety).
6) Vibration isolation treatment of special building structures (if treated, incoming vibration can be effectively reduced)
Therefore, in the vicinity of strong low-frequency vibration sources, both good-quality buildings and poor-quality buildings will be affected by the vibration and noise transmitted by the structure. Therefore, the acoustic consultant will put forward the structural vibration isolation treatment scheme according to the site and architectural design, and cannot judge the poor quality of the building.
