Low Noise Blowers – Why They Are Better

When it comes to leaf blowers, the first thought is usually how irritating they can be. In fact, the majority of blowers that people are familiar with are the ones that are noisy enough to disturb the neighbors. In reality, there are “quiet” leaf blowers, or low noise blowers available that resolve this issue.

So why is this important? It is that some cities want to ban traditional gasoline powered leaf blowers. It all has to do with the level of sound that is produced. Sound level is a measurement of sound pressure expressed logarithmically in decibels [dB(A)]. Any sound that measures 85 dB(A) or above at the ear can cause hearing loss if exposed for long periods of time. To give you an idea of what sounds can be harmful, here are some reference points (check out this infographic for even more examples):

  • Concerts – these measure anywhere from 135 to 145 decibels.

  • Gunshots – depending on the gun, anywhere from 145 to 155 decibels.

  • Shuttle Launch – not an average sound, but you can imagine just how loud they can be. These generally measure anywhere from 165 to 170 decibels.

Anyone who has been to a concert lasting several hours knows that when they leave, ambient sounds appear to be slightly muffled. So we know first hand that prolonged exposure can impact our hearing. This is why when at concerts, gun ranges, and shuttle launches hearing protection is recommended.

So knowing all of this, where does the PB-250LN gasoline powered blower from ECHO fall in terms of decibels? Measured at 50 feet, it is a mere 65 dB(A)! The level of decibels the ECHO blower puts out at the operator’s ear falls well below the range of our examples. It is welcomed in neighborhoods and communities that have complained about leaf blower noise or are considering a leaf blower ban because a low noise blower is around 75% quieter than a traditional blower.

Not only are quiet leaf blowers sound reduced overall, but ECHO has designed the low noise blower to include sound absorbing materials that eliminate the whine typical of older designs. They also use a unique muffler concept that lessens exhaust sounds and incorporate a patented sound attenuator that quiets the air intake system. The fan and cowling were redesigned to lessen the airflow sound while maintaining the efficiency and performance of the device.

A natural question that follows is, “Well what if an electric blower were used? Wouldn’t that help with noise levels?” While the noise level may be reduced on some electric designs, it is not reduced on all that are available. Most still generate a high pitched scream that sounds very much like a shop vacuum. Battery powered blowers may not scream, but performance and running time are sacrificed for the sake of less noise. Corded electric blowers can’t match the power obtained from a gasoline powered blower. Another serious drawback is that these blowers are attached to stationary power outlets by an electrical cord which limits where the user can go.

When it is time to determine the best solution for any leaf blower need, an ECHO low noise blower is the ideal addition to your inventory of lawn care tools.
