I've heard there are telephones out there for the hearing impaired but what I am looking for is a land line telephone for my parents who wear hearing aids but refuse to wear them when using the phone. Both say they get ringing and feedback when using a cordless phone while wearing hearing aids, but when they remove them the volume of the phone isn't sufficient.
So...I am looking for a land line base phone, with speaker phone, and better than average volume and sound clarity. If possible, the phone system would come with one or more cordless phones, also with exceptional volume and sound clarity. Oh, I should also mention that they, and I, are very limited financially so can't spend a lot on this.
If a phone with these features doesn't exist, is there some sort of device that can be attached to the phone to increase volume and sound clarity?
Somewhat related, can anyone define a few things for me:
What is the difference between a 5.8 GHz, DEC 6.0, 9 GHz, and some other numbers and acronyms I can't recall atm.
Thank you for your help!

there are plenty of hearing aid compatible telephones http://www2.panasonic.com/webapp/wcs/stores/servlet/PNAEndecaSearchCmd?N=779832047&No=0&Nr=12001&Ns=&Ntk=MainSearch&URL=vShopSearch&cmTag=true&catalogId=13401&storeId=15001&Ntt=hearing+aid+compatible&cm_sp=SiteSearch-_-MainSearch-_-Consumer
DECT - Digital Enhanced Cordless Telecommunications these phones operate in the 1.9Ghz frequency range - an unlicensed spectrum that the FCC has set aside strictly for cordless telephones.. this is the latest and greatest in cordless phone technology...
5.8Ghz operates in this unlicensed spectrum, there are some other consumer wireless devices that operate in this spectrum, but it is one of the least crowded frequencies - however since it is the highest frequency cordless phone on the market, it also has the least range from handset to base (some 5.8 cordless phones also operate on the 2.4 Ghz spectrum)
2.4 Ghz operates on this unlicenced spectrum with many other consumer wireless devices such as WiFi routers, microwave ovens, wireless video cameras, etc...
900 Mhz phones operate on a crowded unlicensed frequency with many other consumer wireless devices, such as baby monitors, wireless speakers, garage door openers, car alarms, etc... also unless the phone has DSS then it is insecure and can be monitored by a radio scanner... (DECT, 2.4 and 5.8Ghz phones all have some form of DSS, or FHSS)
DSS - Digital Spread Spectrum - a form of encryption to prevent eavesdropping...
FHSS - Frequency Hopping Spread Spectrum - a form of encryption that also continuously searches for the best channel, and keeps changing to the best channel between the handset and base (normally these phones will not have a channel button, because the phone is constantly changing channels on its own)

Looking for a video camera with good audio... any suggestions?

I have a piano recital coming up, and I need a suggestion for a fairly cheap camera with good audio recording capabilities, as the last camera we used recorded the sound absolutely horribly ( i assume it was because the camera was made to only capture the human voice's spectrum ).
I just want something that can capture the full span of sound that a piano can emit without hisses or cracking noises- or if there is no such camera, share some ideas for best recording the event (e.g. maybe a suggested external mic or whatever)... I have one month. Thanks :)
Answer
Camcorder microphones aren't usually professional level, but they aren't bad, either. What they are is poorly located to get audiophile level recording. Way too far away far away from the source of the sound, they'll pick up noise and chatter from close to the camera. If you're filming at the 3-6 foot range, most camcorder audio will work fine. Farther away requires more effort. Bottom line is that proper microphone placement is critical for good recordings.
Depending on the stage setup (if any) at the recital, see if one of the following options is feasible:
1) If the piano is miked into a PA/speaker system, recording the line output of that device onto a CD or other recorder gives some of the clearest possible sound. If you leave your camcorder running continuously during the performance, it's fairly easy to sync the CD audio to your digital video in any of the movie editors and get top notch audio and video. Leave your camcorder running so you only have to sync one spot, not at every scene. Once synced, you can then cut out boring sections of the video. (~$0 expense if they have a CD recording system already in place)
2) If the piano isn't miked, you can use a digital audio recorder. The good ones aren't cheap, but you'll get baby monitor quality sound if you go cheap. Place the recorder in a good location near the piano (test before the recital if at all possible). These small devices are unobtrusive, and can get quality recordings if placed properly. You could use this recording to supplement/replace your existing camera's audio as described above ~ $150 http://www.bhphotovideo.com/c/product/599284-REG/Tascam_DR_07_DR_07_Portable_Digital_Audio.html)
3) You can buy a camcorder with an external microphone jack and get a wireless mic system or a shotgun mic (think teleaudio to match your telephoto zoom). Unfortunately, you tend to get what you pay for on this. Decent ones start at $75 and you still have to figure out where to position the microphone. http://www.bhphotovideo.com/c/search?ci=15708&N=4290441573+4293345063&Ns=p_PRICE_2%7C0
Shotgun microphones (the zoom version of a microphone) are very directional in it's pickup pattern, removing much of the side noise captured by built in microphones. $60+ http://www.bhphotovideo.com/c/product/3646-REG/Azden_ECZ_990_ECZ_990_Super_Cardioid_Shotgun.html
Unless your existing videocamera has an external mic jack, you'll have to factor in the additional cost of a new camera with a microphone input. External microphone jacks have been removed from the feature list of most consumer camcorders. HD cameras with the external microphone jack tend to be ~ $800-$1000
