Testing a silencer from Air Rifle, with Hatsan BT65 SB Elite .22 air rifle. This test was recorded in a very resonant space, were the use of a silencer makes a big difference. To shot without a silencer I was using hearing protection (this gun is loud!). First, 5 shots without silencer, using Combat Destroyer 27.8 grains pellets, then 5 more with silencer fitted. An iron sheet was the backstop, and it barely can be heard blended with the shots without silencer. When using silencer the pellet hitting the backstop can be heard clearly, right after the BT65 discharge.
These 10 shots were recorded near the air rifle, using M-Audio Microtrack 24/96 portable digital audio recorder, working with 24bit resolution and 96KHz sample rate. The limited/compressed audio from cameras was not used.
Next 6 shots with silencer, using the lighter Gamo Pro Hunter 15.4 grains pellets, then 5 more shots without silencer. These last 11 shots were recorded with the microphones next to the target (32.6 yards away from the air rifle). A telephone list was used as a backstop, to reduce pellet impact noise.

Vídeo mostrando como o silenciador (supressor ou redutor) de ruídos da Air Rifle diminui o estampido da carabina Hatsan BT65 SB Elite 5,5mm. O vídeo foi filmado em um ambiente com acústica bastante ressonante (paredes, teto e piso em concreto) onde o som de um disparo com a BT65 é suficiente para te deixar com um bom zumbido na cabeça por alguns dias... Além do conforto de poder atirar sem uso de protetores para audição, o silenciador reduz consideravelmente a possibilidade de incomodar vizinhos mais sensíveis. Para a gravação do áudio dos disparos, um gravador digital com resolução de 24bit e taxa de amostragem de 96KHz foi utilizado, pois o áudio das câmeras é sempre processado através de limitadores e compressores, o que causa grande alteração no envelope dinâmico de amplitude dos sons. Dois chumbos foram selecionados para os testes devido seus pesos contrastantes: o pesado Combat Destroyer (1,8g) e o mais leve Gamo Pro Hunter (1g).
A primeira sequência, realizada com o gravador ao lado da carabina, foi de 5 tiros sem supressor, com chumbo Combat Destroyer, seguida por outra sequência de 5 tiros com o supressor e mesmo chumbo. O alvo era uma chapa de aço atrás de uma sacola repleta de espuma e "plástico bolha" (o material macio deveria segurar o chumbo, mas não foi o que ocorreu... Os chumbos atravessaram como manteiga, fazendo um belo barulho na chapa de aço). Sem o supressor o ruído do impacto na chapa mal é perceptível, com o supressor instalado pode-se escutar tranquilamente o impacto alguns milisegundos após o disparo (alvo estava a 30m).
