Sound art is defined as art that is created using sound as its primary medium. This can include music, sound installations, and other works of art that use sound as their main expressive element.

Sound artists face a number of copyright issues, including copyright infringement, fair use, and public domain. Copyright infringement occurs when someone uses a copyrighted work without permission from the copyright holder. Fair use is a legal defense that allows limited use of copyrighted material without permission from the copyright holder. Public domain refers to works that are not protected by copyright and can be used by anyone without permission.

The fair use doctrine is a legal defense that allows limited use of copyrighted material without permission from the copyright holder. This doctrine is based on the idea that certain uses of copyrighted material, such as criticism, comment, news reporting, teaching, scholarship, or research, do not harm the copyright holder's exclusive rights and are therefore fair.

When determining whether a use of copyrighted material is fair use, courts consider four factors: the purpose and character of the use, the nature of the copyrighted work, the amount and substantiality of the portion used, and the effect of the use upon the potential market for or value of the copyrighted work.

The public domain refers to works that are not protected by copyright and can be used by anyone without permission. This includes works that have never been copyrighted, works whose copyright has expired, and works that have been dedicated to the public domain by their creators.

Sound artists who use copyrighted material without permission may be sued for copyright infringement. They may also have to pay royalties to the copyright holder or get permission from the copyright holder before using the material.

Sound artists who use public domain material do not have to get permission from the creator of the material, pay royalties to the creator of the material, or refrain from using the material for commercial purposes.

Sound artists can protect their own work from copyright infringement by registering their work with the Copyright Office, using a copyright notice on their work, and keeping a record of their creative process.

Sound artists can avoid copyright infringement when using copyrighted material by getting permission from the copyright holder, using the material in a fair use manner, or using the material in a public domain manner.

Sound artists who exhibit their work may have to get permission from the venue owner, pay a fee to the venue owner, and comply with the venue's rules and regulations.

Sound artists who sell their work may have to pay taxes on the sale of their work, comply with the laws of the state in which they are selling their work, and get a license or permit to sell their work.
