Quick Answer
A quality suppressor can reduce the sound of a rifle discharge to around 128-130 decibels (dB), or even lower, depending on the type and quality of the suppressor, compared to the typical 160 dB of a non-suppressed rifle.
Types of Suppressors and Their Effectiveness
When it comes to hunting with suppressors, you’ll typically encounter two main types: full-auto and hunting-specific models. Hunting-specific models are typically more effective at reducing sound levels, with some high-end models capable of reducing the discharge sound to around 120 dB. For example, a SilencerCo Osprey suppressor can achieve a sound level of around 122 dB when paired with a .308 rifle.
Measuring Suppressor Effectiveness
Suppressor effectiveness is often measured in terms of the “sound level reduction” (SLR), which is calculated by subtracting the suppressed sound level from the non-suppressed sound level. A good hunting suppressor should have a minimum SLR of 30 dB, with some high-end models achieving up to 40 dB or more. In practice, this means that the suppressed rifle will sound more like a muffled .22 caliber rifle, making it much more pleasant to shoot.
Hunting with Suppressors: Real-World Experience
When hunting with a suppressor, it’s essential to consider the environmental factors that can affect sound levels. For example, shooting in a canyon or near a body of water can amplify the sound, making the suppressor’s effectiveness less pronounced. In such cases, it’s crucial to choose a suppressor with a high SLR and a durable, long-lasting design. By understanding the capabilities and limitations of your suppressor, you can use it to your advantage when hunting, making it easier to get close to your prey without spooking it.
