Bow String Silencer: Types, Placement & Noise Reduction

What a Bow String Silencer Does

When an arrow is released, not all of the stored energy transfers to the shaft. Some remains in the bowstring as residual vibration — producing anything from a dull buzz to a sharp twang, depending on bow setup and draw weight. A bow string silencer attaches directly to the string itself, adding mass and surface area that absorbs these oscillations before they can sustain and amplify.

This is distinct from a string damper, which mounts on the riser and contacts the string at rest. A silencer travels with the string and dissipates energy continuously as the string returns to brace height.

Common Silencer Types

• Fur silencers (beaver or otter hide): Threaded between the string's strand bundles, these are lightweight, durable, and effective in dry conditions. In prolonged wet weather they can lose their dampening effect.
• Cat Whiskers / rubber silencers: Pre-cut rubber strips tied between strands with an overhand knot. Weather-resistant and easy to replace, with a lighter impact on arrow speed than fur options.
• Puff silencers (yarn-based): Made from wool or synthetic yarn, these offer good vibration absorption and are a popular choice as an archery string noise reducer for traditional setups.
• Slip-on dampeners (e.g., Monkey Tails style): Require no bow press and install in seconds. Speed loss is minimal — typically 1–2 fps total across all attachments — with most string and cable sound eliminated.

Placement Guidance

A common starting point for a bow string silencer is roughly 7–10 inches from each string loop, measured to the center of the silencer. A more precise approach divides the string's working length (loop to loop along the bow) by four and by three, then places the top silencer at the quarter-distance point and the bottom silencer at the third-distance point. This arrangement targets different harmonic frequencies simultaneously, helping the string settle to a thud rather than a prolonged twang.

When separating strand bundles during installation, always use a blunt pick tool — never anything sharp. Cutting or nicking bowstring fibers creates a safety risk. See our guide on bowstring eye types and their effect on string performance for context on how string construction affects accessory installation.

Does a Bow Silencer Affect Speed?

Any mass added to the string will reduce arrow speed slightly. Rubber and slip-on silencers generally have the smallest speed penalty. Heavier fur silencers reduce speed a little more, but remain well within acceptable limits for most hunting and recreational use. For archers focused on a bow vibration dampener solution that balances noise reduction with minimal speed loss, rubber styles are a practical starting point.
