Audio Equipment Vibration
What equipment can detect hidden body wires/audio recording devices hidden on a person (Rat) ?
I see on counter surveillance web sites that there are a lot of bug detectors of many different variations. What model/kind do you know of/recommend that would specifically alert the user of somebody nearby wearing a hidden wire on them or audio transmitters? I am looking for a portable device that I can keep in my pockets to to be notified by vibration? Please provide links.
(BTW I am starting out in the private investigator field).
Thanks!
just wear a tin foil hat...if it turns blue, ufos are monitoring your toilet habits

IsoNode Pro Anti-Vibration Feet - Large (Set of Four) $19.99 The IsoNode isolation feet provide a cost-effective upgrade for your audio and video equipment. The unique IsoNode polymer rejects a wide range of vibration that would enter from underneath the component. The highly compliant IsoNode acts as both a liquid and a solid for superior vibration control. Adhesive backing included. The large size are each 1-1/4" X 3/4" tall and hold 42 lbs.When you add the IsoNode feet to your audio and video equipment, the first thing you will notice is superior resolution and picture quality from video and increased clarity, dynamics and more extended bass response from your audio. As you play your home theater, more subtle improvements can be perceived: greater dimension and depth plus more vivid color from video and enhanced soundstage, smoothness and detail from audio. In fact, every aspect of your home theater is significantly improved! Eliminating vibration and resonance has a profound effect on a home theater system. Which component benefits the most from IsoNode feet? The source (DVD player, CD player, etc.) typically exhibits the greatest benefit, but all of the components in your system will improve by adding the IsoNode feet. The center channel speaker and any speakers in the same cabinet as the components are in critical need of IsoNode feet as they are the main source of harmful vibration.If your component exceeds the weight limit of a set of IsoNode feet, you can easily add additional IsoNode feet under a component to increase the weight capacity. Each large IsoNode foot holds 10.5 lbs maximum and each small IsoNode foot holds 7.5 lbs maximum.Even if your component weighs less than 30 lbs, the large IsoNode feet do have a greater ability to absorb harmful vibration than do the small IsoNode feet. The small IsoNode feet are best if you have height restrictions in your cabinet or want to maintain a lower budget.Isolation TheorySay something. Now cover your ears with your hands and say the same thing again. Sounds different, doesn't it? "Of course," you say, "my ears are covered!" Of course, you're right, but what you're still hearing are vibrations being transmitted directly from your voice box--the tissue of your body is absorbing and releasing the energy from your throat to your ears. Now play something on your home theater system and cover and uncover your ears. Even with ears covered you are still able to hear the music directly through the air from the speaker. In addition, some vibrational energy may be reaching you through the floor and chair in which you are sitting--especially from the subwoofer.Your CD or DVD player is like your body and the equipment stand is like your chair. As the system plays the chassis is absorbing the radiated energy through the air and the conducted energy through the floor and stand. The chassis starts to resonate and conducts these vibrations into the DVD disc, the player's electronic circuitry and the mechanical parts. As these parts vibrate the information the player |

Radio Equipment $119.48 High Quality Content by WIKIPEDIA articles Radio equipment, as defined in Federal Information Management Regulations, is any equipment or interconnected system or subsystem of equipment (both transmission and reception) that is used to communicate over a distance by modulating and radiating electromagnetic waves in space without artificial guide. This does not include such items as microwave, satellite, or cellular telephone equipment. Telecommunication is the transmission of messages over significant distances for the purpose of communication. In earlier times, telecommunications involved the use of visual signals, such as smoke, semaphore telegraphs, signal flags, and optical heliographs, or audio messages via coded drumbeats, lungblown horns, or sent by loud whistles, for example.

Sound Vibration: Microphone System $111.53 The aim of this project is to develop a prototype Intelligent Microphone System. The system is able to adjust the height of the microphone automatically to suit the different speakers height so that manual adjusting is not need, which is more reliable and time effective. This height detection is done by means of continuous monitoring the audio signal produced by the speaker while speaking.Unlike the existing microphone system, this project aims to use BASIC Stamp 2P 40pin to decide whether the audio level is high or low and according to that it controls the motor. Motor is using power screw method for vertical translation and eventually the microphone moves up or down accordingly. Unfortunately the prototype described in this thesis does not fully minimize the noise level. So as a matter of fact the noise level is also affects the system. But solution to this problem is also described as a feature improvement. Moreover many calibrations were held for the system. In the end it can be conclude that this project will be useful in the daily life, which means no need to adjust the microphone stand manually.

Home Audio Speakers
Sound, also perceived as the sense of hearing, is an integral part of our lives. Without the ability to hear or reproduce sound we are not complete. Sound is the vibrations that travel through air and can be sensed by our ears. Thus it is a medium of communication. It is used to gather information and knowledge about properties of the environment surrounding us. Sound can travel through air, water, and solids. These help sound waves travel and are known as medium. In normal conditions, human can hear a varied frequency range. But, sometimes we need to amplify the sound output for better quality of hearing. This requires the help of speakers.
Speakers are devices, which convert electromagnetic signals into sound vibrations. Thus speakers are machines that enable us to hear sounds, which have their origin somewhere else. Speakers, also termed as loudspeakers are attached to an audio system, which provides the electromagnetic signals that are then reproduced in the wavelength, which humans can decipher. The loudspeaker is the most variable element in an audio system, and is responsible for marked audible differences between systems.
Home audio systems have come a long way since their inception as just another loudspeaker system. They have become a part and parcel of our every day lives. Today, many versions of home audio systems have evolved into our homes. Technological enhancements have made sure that we can take our audio or sound system wherever we go. As speaker systems are the most important part in the output of sound, they have evolved greatly. Many versions of speaker systems are available in the market today. Depending upon your choice of price and your perception of quality, you can opt for the one that best caters to your requirements.
Speakers are an integral part of any audio system, be it a simple radio or a home theatre system. Home audio speakers are generally multi-drive systems, i.e. they contain two or more drive units. These include woofers, midranges, tweeters, and sometimes horns or super tweeters. A home theatre system is complete only if all the above mentioned add-ons are attached with it to give a theatre-like sound experience. In home audio speaker specifications, the speakers are classified as "N-way" speakers. It indicates the number of bands of different frequency into which the system divides the sound. A 2-way system consists of woofers and tweeters, a 3-way system consists of mid-range speakers with a combination of woofers and tweeters. It depends upon person to person; rather there exists different perceptions towards the quality of sound and thus the drives in a speaker.
If and when you decide upon purchasing a home audio speaker system, you will be spoilt for choice. They come in various ranges of quality and pricing, thus you need to decide carefully what caters to your specific set of requirements. Good audio companies make available a host of choices for speaker systems that can gel with your audio systems. They also provide different designs and creations of speakers that fit into your décor. You can place your systems in such a way that it gives you the optimum output.
