When discussing firearms, suppressors, and hearing protection, the term "decibel" frequently comes up. But what exactly are decibels, and why should you care about them, especially if you're a gun owner? In this blog post, we'll explore what decibels are, what levels are considered hearing-safe, how suppressors help reduce noise, and why investing in a suppressor from Black Creek Firearms could be a smart decision for your hearing and overall safety.
What Are Decibels?
Decibels (dB) are a unit of measurement that quantifies the intensity of sound. The decibel scale is logarithmic, meaning a sound measured at 100 dB is ten times more intense than a sound at 90 dB, not just a little louder. This non-linear scale helps us understand the significant differences in sound levels and why small increases in dB can have a dramatic impact on our ears.
What Decibel Level Is Truly Hearing-Safe?
According to the National Institute for Occupational Safety and Health (NIOSH), exposure to sounds at or above 85 dB over prolonged periods can lead to hearing loss. This is the threshold at which hearing protection becomes necessary. For reference, normal conversation typically occurs at about 60-70 dB, and busy traffic might hit 85 dB.
However, "hearing safe" can vary depending on exposure time. For example, exposure to sounds at 100 dB for more than 15 minutes can cause hearing damage, while sounds at 120 dB can cause immediate harm. Ideally, consistent exposure should remain below 85 dB, especially if no hearing protection is used.
How Loud Are Everyday Sounds?
Normal conversation: 60-70 dB
Busy traffic: 85 dB
Concerts: 100-120 dB
Gunshots: 140-170 dB (depending on the firearm)
These examples illustrate why protecting your ears is crucial, especially in environments where loud sounds are common.
Decibel Reduction with Suppressors: What Are We Doing?
Suppressors, also known as silencers, work by trapping and slowing down the expanding gases that follow a bullet when it's fired. This process reduces the sound of the gunshot, often by 20-35 dB depending on the suppressor and firearm combination.
While this reduction might not make the gunshot silent (as Hollywood often portrays), it can bring the sound down to a more manageable level. For example, an unsuppressed firearm can produce around 165 dB of sound. With a high-quality suppressor, this might be reduced to around 130-135 dB.
What's Not Necessarily Hearing Safe, But Probably OK Without Hearing Protection?
Even with suppressors, gunshots are often still above the "hearing-safe" threshold of 85 dB. However, reducing the sound to 130-135 dB makes it more manageable in short bursts. For comparison, a rock concert often ranges between 100-120 dB, and while it might not be comfortable, most people can tolerate it for short periods without immediate harm.
When using a suppressed firearm, the reduction to 130-135 dB can make shooting more comfortable, though hearing protection is still recommended for extended use. However, in a high-stress situation, like home defense, you may not have the luxury of putting on ear protection.
Real-World Example: Suppressed vs. Unsuppressed Firearm
An unsuppressed firearm can reach levels around 165 dB, which is far above the threshold for immediate hearing damage. With a suppressor, this level might drop to around 135 dB. While this is still above the 85 dB "hearing safe" level, it's a substantial reduction that can make a significant difference in protecting your ears during a short engagement.
In situations like home defense, where you might need to grab your rifle quickly, a suppressor could be the difference between temporary hearing discomfort and permanent hearing loss.
