Did you ever have a wound or sore that simply does not heal no matter what you try? Perhaps it's even been treated by a physician, but still remains.
This type of wound is characterized by skin deterioration to the point where the underlying tissue is exposed. Such wounds are also called sores or ulcers and can have a variety of causes. But they all have one thing in common --- prompt treatment is important to prevent infection and further deterioration of the surrounding area.
Here are some examples of slow-healing wounds:
Ulcers often form on the leg and foot as a complication of diabetes Pressure Sores (also known as bedsores) are caused by constant pressure on an area of the skin Venous Skin Ulcers develop when veins don't allow blood to flow back to the heart normally. A Wound or Open Sore may have many different causes such as incisions, lacerations, abrasions, puncture, penetration, and gunshot
If you have a wound that will not heal in a reasonable period of time, it is always wise to seek medical treatment. But is there something you can do initially to prevent a wound from getting worse and help it heal more quickly?
According to foot surgeon, Dr. Paul R. Glaser, the answer is yes. He often advises his patients to use a natural-ingredient, over-the-counter topical spray and foam to speed healing on foot wounds including diabetic ulcers, infected ingrown toenails, psoriasis, and post-op lesions. [1]
The results he has seen are often dramatic:
Chronic diabetic ulcers have been healed in 6 weeks. [2] Pain and burning is greatly relieved when regularly applied post surgery. [3] The risk of infection is greatly diminished with regular use. [3] Overall healing time after a common surgical procedure has been reduced to 2 to 3 weeks compared with a more usual 3 to 5 weeks with topical antibiotics alone. [4]
Why can a natural product often heal wounds better than prescription drugs? The answer is simple... By using ingredients that support the natural action of the body's immune system, you can achieve the desired result in a safe, non-invasive manner.
For example, some traditional wound care treatments may be quite expensive and have side effects such as higher blood pressure, higher eye pressure (glaucoma), retention of fluid, skin thinning, red lesions and mood swings.
An effective natural treatment can help fight infection and heal the wound without side effects and at significantly lower cost.
For example, the natural treatment Dr. Glaser recommends contains an enzyme (lysozyme) that is found in the tears, saliva, mucus, urine and salt water body fluids. Lysozyme targets harmful bacteria while sparing beneficial ones. The treatment also contains sea salt with all the trace minerals left intact. The sea salt solution provides an ideal pH environment for the lysozyme to operate, as well as nutrients that support new cell growth. This creates a product that's so safe it can be sprayed directly in the eyes or mouth, yet effectively supports and speeds the body's natural healing process.
While you should always consult with your physician for any chronic medical condition, you may find a natural product will encourage your body's own innate healing ability better than conventional preparations.

The concept of forensic audio investigation may have become popular in recent years along with the forensic sciences in general but it's been in practice since World War II. With audio use in full swing for radio transmissions across long distances, scientists were trying to identify the voices of their enemies among the many radio broadcasts that took place on open frequencies. The work done in forensic audio investigation today is based on the pioneer work of those scientists.
Specifically, forensic audio has to do with any type of audio of an evidentiary nature. In modern cases, law enforcement or other legal professionals (e.g., defense attorneys and prosecutors) will turn to a forensic audio examiner to perform any one of a number of services where audio is concerned.
In many cases these specialists are hired on a contract basis.
While the most common Hollywood portrayal is audio enhancement with a few twists of a knob (if only it were so easy) there is a great deal of work that can be done:
Audio Enhancement - the most common and offered by just about every forensic audio company you can find. Audio Authentication - geared toward tape and digital formats Forensic Transcription Speaker Identification
There are also a number of other services or procedures that can be classified in their own right as a specialty process or "miscellaneous" in terms of categorization. This article will focus specifically on Audio Enhancement and Authentication.
Audio Enhancement
Audio enhancement is the most common and well known service where forensic audio is concerned.
It's not likely that one can take a garbled and mangled inaudible conversation and "tweak it" to produce clear speech that is intelligible. While audio enhancement isn't specifically focused on speech, that is usually the intent behind cleaning up or enhancing audio for legal purposes. It's a means of reducing or filtering out unwanted noise from a poor recording in order to clear up the speech that's covered with noise or is a victim of poor recording methods.
A forensic examiner is not a miracle worker however, and while modern software and equipment has provided a variety of tools to improve the quality of speech in a recording, there are still limitations. When it comes to enhancing speech, you can't fix something that's just not there. If the recording doesn't contain the robust elements of someone's speech, and the equipment only picked up bits of a word or phrase, there is no magic software to fill in the blanks. Enhancement techniques can sometimes have fantastic results with intelligibility, but more often would be a disappointment to the layperson.
In terms of speech enhancement, an examiner can offer critical listening in combination with forensic transcription and speech decoding methods to help identify and discern what is being said. Again, technology can only do so much so an examiner with linguistics and phonetics experience is usually best for the job. However, if the speech waveform isn't picked up by the recording device or is masked by noises of the same frequency range, he won't be able to decipher the speech.
Forensic audio enhancement sometimes simply involves increasing the volume of a whisper from a suspect where traditional playback - even at high volume - can't help an individual understand the utterance. Audio enhancement offers the most benefit in situations where noise can be eliminated or at least reduced so as not to distract the listener from the speech. Enhancement techniques are quite good at getting rid of electronic buzzing or hum and other noises such as tape hiss, the crackles and pops of a phonograph record or the beeping of a backing truck, open car door, low battery warning of a fire detector, etc. Enhancement used in this way is often called improving the listenability of the recording. Unintelligible speech isn't made intelligible but the recording is easier on the ears.
Audio Authentication
Authenticity is an important part of legal matters where evidence is concerned. This is especially true when it comes to audio that is or will be entered into evidence in a criminal or civil matter. As technology advances, it becomes progressively easier for an individual to tamper with a recording.
Audio authentication - either involving tape authentication or digital file authentication - is a way to ensure that the audio being utilized as evidence has not been tampered with in some way.
Not only will a forensic audio examiner use software to examine the actual recording, but authentication involves examining the physical tape itself and its casing.
This includes:
Checking the tape for splices Examining the tape's plastic shell to check for prying or disassembly A process of examining the tape call magnetic development
Magnetic development involves using a magnetic liquid called ferrofluid in the examination of audio or video tape. The ferrofluid allows the forensic examiner to see the magnetic patterns on a tape. The types of things the audio engineer would look for include magnetic signatures left by stopping, pausing and starting the recording process. It can also be possible to tell if the tape has been recorded over or simply erased and left blank.
Newer software provides an edge when it comes to detecting authenticity in audio as it looks into variances that could lead to falsification of a recording - particular in tape recordings:
Equipment noise - hums, pops, varying pitch in inconsistent forms over the whole of the recording Fading - Any gradual or sudden decline in volume that effects the interpretation of noise or dialogue. If the sound cuts out completely that becomes a gap in the recording Gaps - Any segment where there is a change (often unexplained) in the content or context of an audio recording. A perfect example of this is the infamous Watergate recording where there is an 18 and ½ minute gap in the recorded audio that was later discovered to be an overlaid recording of electrical interference. Transients - These are clicks or pops and other "attack" sounds within a recording and may signify that there has been a splice or some other alteration to the recording
There are a number of methods that are used to authenticate a recording, checking it specifically for originality. An obvious and important tool that a forensic audio examiner has is the ear. Critical listening affords a great deal of benefit and it takes training and experience to know what to listen for while playing a track over and over.
In some cases, an examiner may have to run through a section of audio many dozens of times. They examine bits of a conversation or sections of a recording to fully understand the sounds - including both foreground and background sounds. If something stands out the examiner will further investigate that specific segment using their trained ear to discern if the recorded event is authentic or not.
Beyond listening, the examiner utilizes physical inspection as well as spectrum and waveform analysis to visually inspect the quality and construct of a specific piece of audio. All of these methods come together allowing the examiner to certify the authenticity of a tape recording.
Things become more difficult when a recording is made using a digital recorder that creates audio files such as.wav or.mp3. While many of the above methods may be useful with a recording that originated as a digital file, it is somewhat easy for a knowledgeable person to edit the file without leaving any known sign of doing so.
One promising method of digital authentication is the use of ENF (electric network frequency) data. Whenever someone is recording while plugged into an electrical outlet or using a battery operated device within an ENF magnetic field, their recording will include a 50Hz or 60Hz (depending on country) waveform signature. This signature can be compared to an ENF database to possibly determine where and when the recording was made, whether it's an original or a copy, or whether it was edited or altered in anyway. Digital audio authenticity examination, and more specifically the use of ENF, is in its infancy and has a way to go before forensic audio examiners reach the level of sophistication that has been achieved with authentication of analog tape recordings.
The use of software to determine authenticity and enhance audio is just the beginning when it comes to forensic audio. Depending on the situation, additional specialty services or skills may need to be applied such as speaker identification and the analysis of gunshot sounds to determine if more than one weapon was used, which type of firearm was used, or the sequence of the shots fired. Forensic audio is a robust trade that encompasses a number of specialists who work together to bring clarity through the study and examination of audio.

What is exposure to loud noise?
Many people have no idea of the possible extreme consequences of being exposed to loud noise, whether the noise exposure is over a long term or in short, sharp exposures such as when your vehicles air bags deploy. Exposure to loud noise can cause hearing loss and tinnitus. Tinnitus is the condition that millions of people suffer from that leaves them hearing a ringing in their ears or buzzing or chirping sounds.
Examples of exposure to loud noise
Examples of incidents that could cause an over exposure to loud noises and result in hearing loss and tinnitus include sudden explosions like fireworks, gunshots, planes taking off closely overhead or the impact of an accident such as vehicles colliding.
Exposure to loud noises in the workplace
Prolonged exposure to loud noise is often to blame for cases of hearing loss and tinnitus. People who work in factories where loud machinery is used are routinely subjected to over exposure to loud noise. Infantrymen also typically experience extremely loud exposure noise.
Musicians who participate in large-scale concerts as well as the concert goers themselves face exposure to loud noise on a regular basis, often without any form of protection. People that frequent nightclubs or loud bars also experience tinnitus and fuzzy hearing from the exposure to loud noises typically present in these venues.
The effects of exposure to loud noises
When loud noises interfere with one's hearing or induce tinnitus, there is an indication that cochlear damage has occurred. The cochlea is the part of the inner ear that detects pressure and transmits electrical impulses through the auditory nerve, sending the sound transmission to the brain.
The majority cochlear damage cases stem from regular exposure to loud noise or from the person being in a motor accident which results in sudden exposure to extremely loud noises.
Tinnitus from exposure to loud noise
Habitual users of MP3 players are also at serious risk of exposure to loud noise with the resultant hearing loss and tinnitus as risks. Tinnitus caused by exposure to loud noise is best treated using alternative medicine such as homeopathy. There are also several herbal remedies that can be explored depending on the severity of the tinnitus.
How to avoid exposure to loud noise
The best defense against tinnitus caused by exposure to loud noises is wearing protective hearing in all situations that could put you at risk. Even the cheapest foam earplugs can reduce the exposure to loud noises quite dramatically.
If you have already been diagnosed with tinnitus, consult a doctor to learn about the treatment method that will work best for you and be sure to take preventative measures if you even suspect you might be at risk of exposure to loud noise.
