大量的观察表明，圆蛛在捕获猎物、求偶和养育幼蛛的过程中会对网传振动做出反应，但很少有对蜘蛛网振动的物理学分析。使用测量或估计的物理特性蜘蛛和网络从以前的文献中，方程的开发模型的网络蜘蛛系统在各种频率的信号的响应。在大多数飞行昆虫的翅膀振动产生的声音频率范围内（约50-1000 Hz），共振现象不会影响大多数圆网中的信号传输。在1000赫兹以上，网中的单个股可以共振，但衰减应该防止显著的传输，至少对于横向振动。对于频率低于约30 Hz的信号，蜘蛛或网内其他大型物体的共振可能会显著影响传输。
Numerous observations indicate that orb spiders react to web-borne vibrations during prey capture, courtship and the rearing of young, but there have been very few analyses of the physics of spider webs undergoing vibration. Using measured or estimated physical properties for spiders and webs from previous literature, equations were developed that model the response of web-spider systems to signals at various frequencies. Resonance phenomena do not affect signal transmission in most orb webs in the frequency range of sound produced by the wingbeats of most flying insects (about 50-1000 Hz). Above 1000 Hz, individual strands in a web could resonate, but attenuation should prevent significant transmission, at least for transverse vibrations. For signals with frequencies below about 30 Hz, resonant vibrations of the spider or other massive objects within the web could affect transmission significantly.
