Bien pour utilisation à main levée. Sortie analogique inutilisable.
Grosse déception avec ce Sonomètre. Les fonctionnalités de base sont au rendez-vous. La précision est correcte. Et il y a même quelques bonnes surprises avec une vis de calibration, et une vis de fixation pour montage sur trépied. Si vous voulez utiliser ce sonomètre en utilisation de base "à main levée", très bien. Mais alors, pourquoi cette mauvaise note? Parce que j'avais acheté ce sonomètre spécialement pour relier la sortie analogique à un oscilloscope afin de pouvoir tracer les variations de niveau sonore. Hélas, à la sortie "AC", le sonomètre fournit un signal totalement inutilisable. À titre d'exemple, j'ai joint à ce commentaire un graphique montrant ce que je lis lorsque je balance un signal avec une amplitude de 100dB SPL. Si quelqu'un peut interpréter ça, merci de me le dire. À moins tout simplement que mon exemplaire ne soit défectueux? Bref, je renvoie le produit dés que possible...

Accurate, and a great value!
I have an older DB meter that does straight readings. I was looking for something that I could use for averaging and finding peak volumes so I gave this a try. It's not at all expensive, is easy to use, and seems to work correctly. I have a high end calibrated source for my older meter, and when I tried it on the Extech it read exactly the correct value. So in a static situation the meter is very accurate. While I don't have any way to test it for peak or average readings, I'm guessing that it's probably pretty darn close. I plan on using this for measuring shop machine noise levels, and also for monitoring sound levels for the PA for a jazz band I play in. If you need a DB meter, this one will do a good job at a great price.
