What are the hazards of central air conditioning noise to human body?

All noise will have an impact on physical and mental health, and the harm of low-frequency noise is more profound. Low-frequency noise generally refers to sound with a frequency below 500 Hz. Common sound sources are elevators, transformers, central air conditioners (including cooling towers) and traffic noise.

Low-frequency noise can directly reach people's ear bones, which will make people's sympathetic nerves nervous, tachycardia, hypertension and endocrine disorders. People are forced to accept this kind of noise, and it is easy to have troubles, excitement, irritability and other bad emotions, and even lose their minds. If it is disturbed by low-frequency noise for a long time, it will induce neurosis such as neurasthenia, insomnia and headache, and even affect the fetus in the pregnant woman's abdomen.

The solution of air conditioning noise is 1:

Pay attention to shopping. This seems simple, but it is also the most crucial point. When consumers buy household central air conditioners, they should choose products with low noise and good mute effect.

Solution to air conditioning noise 2:

Vibration and noise reduction measures. Attention should be paid to anti-vibration and noise reduction measures when designing and installing air conditioners. At present, many manufacturers pay attention to noise reduction measures in product design and production. For example, some factories use horizontal scroll compressors with low noise and small vibration, and adopt sound insulation covers; The compressor and the built-in water pump adopt a vibration damping base; Stick 13mm thick glass wool sound-absorbing composite material in the panel; The fan adopts wing blades with high efficiency and low noise, the speed of the fan is controlled below 720 rpm, and variable speed adjustment is adopted to reduce the noise at night; All the connecting pipes and supports in the unit adopt shock absorption measures, which can reduce the noise of household central air conditioning, and this measure has achieved good noise elimination and mute effect.

Air conditioning noise solution 3:

When installing the household central air conditioning unit, the outdoor unit should be installed on the ground as far as possible, and the base should be padded with damping blocks or rubber with the thickness of 10 ~ 15 mm to keep the unit stable; Damping hoses shall be used for all pipes connected with the outside; The air intake and exhaust should be unobstructed to reduce backflow.
