Woofers are generallyused to cover the lowest octaves of a loudspeaker's frequency range. In two-way loudspeaker systems, the drivers handling the lower frequencies are also obliged to cover a substantial part of the midrange, often as high as 2000 to 5000 Hz; such drivers are commonly termed...

Waves don't always zap through the air from transmitter to receiver. Depending on what kinds (frequencies) of waves we want to send, how far we want to send them, and when we want to do it, there are actuallythreedifferent ways in which the waves can travel: 1) By line of sight; ...
An equalizer (also called an “EQ”) isan audio filter that isolates certain frequencies and either boosts them, lowers them, or leaves them unchanged. Equalizers are found on a wide array of electronic devices. Is there an app to improve sound quality? Equalizer FXallows you to improve your...

, 2000), and the spectral power of the variability of the RR interval was modulated by vagal influences at frequencies <0.4373 Hz (Moguilevski et al., 1996). Thus, the spectral power of the RR interval variability measured in our high-frequency range reflects the activity of the ...
hiking and walking in various areas that aren't safe. Ideally, this dog needs to be exposed to all the elements of nature so that the conditions during an actual task don't take him by surprise.An average dog can hear sounds between frequencies ranging from 40 Hz(赫兹) to 60 kHz,which...

douglasfilm:A person at 20 years old can hear a much wider range of frequencies compared to an 80 year old. Audio Masterclass replies to douglasfilm:20 Hz to 20 kHz is 10 octaves. So an older person who can only hear up to 10 kHz still has 9 octaves left. DM ...
Such frequencies require larger components designed to handle lower speeds of vibration. Speakers that handle the broad middle range of audio frequencies (typically between 20 Hz and 2,000 Hz) are called woofers. Woofers are generally at least several inches larger than tweeters, and their bigger...
