Flutter and hum explained

Industrial noise comes from a huge variety of sources. This includes things like generators and compressors. In addition, some forms of gas can get noisy when you transport or vent them. That is why we design and supply first class natural gas silencers. To do so, we use special software to ensure our models can incorporate into your systems.

One thing you might not be aware of is that pipelines produce noises that can negatively impact your health. Gas lines in particular produce a phenomenon of low and extra-low frequency sound waves. They occur due to the transmission of high pressure natural gas through the set ups. These noises are referred to as flutter and hum.

What is flutter?

This is a persistent pulsating airborne pressure wave. It radiates from pipelines. It is a problem that affects the immediate area. You will find that it sounds like the rumbling you can hear from distant thunder. It also feels like the pulsations originating from a helicopter that is flying in the distance.

The big issue is the sound can penetrate houses and feels like a vibration in your ears and head. Another place where you can feel flutter is outside as a discomfort because of interior organ resonance.

What about hum noise?

This is an invasive and persistent low frequency droning, rumbling, or humming. It is not audible to everyone. It tends to resonate in enclosed structures, causing vibrations/sounds between 1 and 50 hertz. Hum waves can move over 25 miles from their origin and expand over an area.

The hum is usually felt more than heard because it is a sputtering tonal noise. It is also an accompanying vibrotactile sensation. People often describe it like numerous intensities of idling diesel engines that are always operating outside their property. Little is known about hum, making it the more unsettling of the two.
